Solve 2x + 3 = 7.
x = 3
x = 4
x = 2
x = 1
Subtracting 3 from both sides gives 2x = 4, and dividing by 2 yields x = 2. This is a straightforward linear equation.
Calculate the area of a rectangle with a length of 5 and a width of 3.
25
10
8
15
The area of a rectangle is found by multiplying its length by its width, so 5 x 3 equals 15. This is a basic application of the area formula.
Evaluate the expression: 3^2 + 4.
12
9
13
7
First calculate 3^2 which is 9, then add 4 to get 13. This follows the order of operations where exponents are computed before addition.
Determine the slope of the line that passes through the points (1, 2) and (3, 6).
2
4
3
0
Using the slope formula (y2 - y1) / (x2 - x1), we have (6 - 2) / (3 - 1) = 4/2 = 2. The slope indicates the steepness of the line.
Simplify the expression: 5x - 3x.
8x
3x
2x
5x
Combine like terms by subtracting the coefficients: 5x minus 3x gives 2x. This reinforces the concept of combining similar terms in algebra.
Solve the equation: x/2 + 1 = 4.
x = 6
x = 2
x = 4
x = 8
Subtract 1 from both sides to get x/2 = 3, then multiply by 2 to find x = 6. This demonstrates basic manipulation of linear equations.
Expand the binomial: (x + 2)^2.
x^2 + 2x + 4
x^2 + 2
2x^2 + 4x
x^2 + 4x + 4
Using the formula (a + b)^2 = a^2 + 2ab + b^2 with a = x and b = 2, we get x^2 + 4x + 4. This is a standard binomial expansion.
Solve for x: 3x - 5 = 10.
x = 10
x = 0
x = 15
x = 5
Add 5 to both sides to get 3x = 15, then divide by 3 to find x = 5. This problem reinforces basic equation solving techniques.
Evaluate: 2(3 + 4) - 5.
8
12
7
9
First compute the expression inside the parentheses: 3 + 4 = 7. Multiplying by 2 gives 14, and subtracting 5 results in 9.
Which of the following equations is in the standard form of a quadratic equation?
ax^2 + bx + c = 0
ax^2 + bx = c
x^2 + bx = c
ax + b = 0
The standard form of a quadratic equation is ax^2 + bx + c = 0, which clearly shows all the coefficients and the constant term. This form is essential for applying methods like factoring or the quadratic formula.
Find the value of x in the equation: 4(2x - 1) = 3x + 5.
2
3
1.8
2.5
Expand the left side to get 8x - 4 = 3x + 5. Subtract 3x from both sides and add 4 to both sides to obtain 5x = 9, so x = 9/5 which is 1.8. This problem tests multi-step equation solving.
What is the median of the following set of numbers: 3, 7, 9, 5, 11?
11
9
5
7
When the numbers are arranged in order (3, 5, 7, 9, 11), the median is the middle number, which is 7. This illustrates the concept of median in a data set.
Simplify the expression: (2x^2 * 3x) / (6x^2).
x
6x^3
1
6x
Multiply the numerator to get 6x^3, then divide by 6x^2. Cancelling the common factors results in x. This tests basic operations with exponents and fractions.
Solve for y: 2y + 3 = 15.
5
6
9
7
Subtract 3 from both sides to get 2y = 12, and then divide by 2 to find y = 6. This equation reinforces simple operations to isolate a variable.
Which of the following functions is linear?
f(x) = √x
f(x) = 2x + 3
f(x) = x^2
f(x) = 1/x
A linear function has the form f(x) = mx + b where m and b are constants. f(x) = 2x + 3 fits this description, making it the correct choice.
Solve the system of equations: x + y = 10 and x - y = 2.
x = 5, y = 5
x = 7, y = 3
x = 6, y = 4
x = 8, y = 2
Adding the equations gives 2x = 12, so x = 6. Substituting back into one of the equations yields y = 4. This demonstrates solving a system of linear equations using the elimination method.
Factor completely: x^2 - 9.
x(x - 9)
(x + 3)(x - 3)
(x + 9)(x - 1)
(x - 3)^2
The expression x^2 - 9 is a difference of squares, which factors into (x + 3)(x - 3). Recognizing patterns such as the difference of two squares is key in factoring.
If f(x) = 3x - 2, find the value of x for which f(x) = 10.
3
10
12
4
Setting f(x) equal to 10 gives 3x - 2 = 10. Adding 2 to both sides and then dividing by 3 results in x = 4. This demonstrates finding the input corresponding to a given function output.
Solve the equation: 2(x - 1) - 3(x + 2) = 4.
x = 12
x = -4
x = 4
x = -12
First, distribute the numbers to obtain 2x - 2 - 3x - 6 = 4, which simplifies to -x - 8 = 4. Adding 8 to both sides yields -x = 12, so x = -12. This question requires careful distribution and combining like terms.
A right triangle has legs measuring 6 and 8. What is the length of the hypotenuse?
10
9
8
12
Using the Pythagorean theorem, a^2 + b^2 = c^2, we compute 6^2 + 8^2 = 36 + 64 = 100, so the hypotenuse c = √100 = 10. This problem applies the fundamental concept of right triangle geometry.

QuizTest & Worksheet Practice Test Cheat Sheet

  1. Master the quadratic formula - The quadratic formula x = (−b ± √(b² − 4ac)) / (2a) is your go-to tool for conquering any quadratic equation without the guesswork. Simply identify a, b, and c, plug them in, and watch the magic unfold - even the trickiest discriminant won't stand a chance. Practice with different coefficients and you'll solve parabolas like a math wizard in no time.
  2. Understand the Pythagorean theorem - a² + b² = c² is the ultimate cheat code for right-angled triangles, letting you find any side length in a flash. Whether you're calculating ladder heights, designing ramps, or just flexing your geometry muscles, this theorem has your back. Keep practicing with different triplets and you'll decode triangles with ease.
  3. Familiarize yourself with trigonometric ratios - Sin θ = opposite/hypotenuse, Cos θ = adjacent/hypotenuse, and Tan θ = opposite/adjacent are your tag-team partners in angle-solving missions. Use mnemonics like SOH-CAH-TOA to lock these definitions into your brain forever. Soon you'll be tackling angle problems faster than a calculator can load.
  4. Learn the distance formula - √((x₂ − x₝)² + (y₂ − y₝)²) is basically your high-tech ruler for the coordinate plane. Whether you're plotting treasure maps or tracking line segments, this formula delivers precision every time. Practice by plotting points and calculating distances to become a grid-master.
  5. Practice the area of a circle formula - πr² turns radius measurements into area answers in an instant. Circles pop up everywhere - from wheels to orbits - so mastering this formula is pure gold for problem-solving. Draw a few circles, measure radii, and compute their areas to see π in action.
  6. Understand arithmetic progression (AP) - The nth term an = a + (n − 1)d describes a sequence where each term "d" steps from the last. Whether you're saving coins or counting carrots, this formula maps out linear patterns perfectly. Try crafting your own sequences to see how first term and difference shape the series.
  7. Memorize surface area and volume formulas - For cylinders (V = πr²h, SA = 2πr² + 2πrh), spheres (V = 4/3 πr³, SA = 4πr²), and cones (V = 1/3 πr²h, SA = πr(r + √(r² + h²))). These equations unlock the 3D world, from soda cans to ice-cream cones. Sketch each shape and plug in numbers to see how dimensions affect capacity and cover.
  8. Learn properties of similar triangles - Corresponding angles are equal and corresponding sides are proportional, making complex shapes manageable. This concept helps you solve geometry puzzles by breaking big triangles into smaller, familiar pieces. Grab a ruler, draw pairs of triangles, and test their similarities to sharpen your skills.
  9. Understand basic probability - P(event) = Number of favorable outcomes / Total number of outcomes is your passport to the world of chance. From rolling dice to drawing cards, this formula quantifies uncertainty in a neat fraction. Conduct simple experiments - flip coins, roll dice - and compare your results to theory.
  10. Familiarize yourself with laws of exponents - aᵝ × a❿ = aᵝ❺❿, (aᵝ)❿ = aᵝ❿, and a❰ = 1 are the power rules that turn intimidating expressions into cakewalks. Use these laws to simplify algebraic problems, tame exponential growth, and explore logarithms later on. Challenge yourself by expanding and contracting powers with these handy shortcuts.
