Solve for x in the equation 2x - 4 = 10.
6
7
5
8
To solve 2x - 4 = 10, add 4 to both sides to obtain 2x = 14, then divide both sides by 2 to find x = 7. This step-by-step process confirms that 7 is the correct answer.
Factor the quadratic expression x^2 - 5x + 6.
(x - 1)(x - 6)
(x + 2)(x - 3)
(x - 2)(x + 3)
(x - 2)(x - 3)
The factors of x^2 - 5x + 6 are (x - 2) and (x - 3) because -2 and -3 add to -5 and multiply to 6. This is the standard method for factoring quadratic expressions.
Which element has the chemical symbol 'O'?
Osmium
Gold
Oganesson
Oxygen
The chemical symbol 'O' represents Oxygen in the periodic table. The other elements have different symbols, so Oxygen is the correct answer.
According to Newton's Second Law, what is the correct formula relating force, mass, and acceleration?
Force = Acceleration / Mass
Force = Mass - Acceleration
Force = Mass + Acceleration
Force = Mass x Acceleration
Newton's Second Law is accurately expressed as Force = Mass x Acceleration (F = m x a). The other formulas do not correctly express the relationship between these variables.
Which organelle is known as the 'powerhouse of the cell'?
Mitochondria
Endoplasmic Reticulum
Nucleus
Ribosome
Mitochondria are responsible for producing most of the cell's energy, which is why they are called the 'powerhouse of the cell.' The other organelles perform different functions within the cell.
Which event is considered a catalyst for the French Revolution?

The American Declaration of Independence
The storming of the Bastille
The fall of the Berlin Wall
The storming of the Bastille in 1789 is widely recognized as a key event that sparked the French Revolution. The other events are associated with different historical periods and contexts.
Which literary device assigns human characteristics to non-human entities?
Metaphor
Alliteration
Personification
Simile
Personification is the literary device that gives human traits to inanimate objects or abstract concepts. The other terms refer to different figures of speech and stylistic choices.
Which continent is the largest by area?
Africa
Asia
North America
Antarctica
Asia is the largest continent in terms of land area. The other continents, while significant, do not cover as much land space.
What does the principle of supply and demand describe?
The reason behind technological innovations
The correlation between population growth and resource depletion
How prices fluctuate based on product availability and consumer desire
The relationship between product quality and consumer satisfaction
The principle of supply and demand explains how the availability of a product and consumer interest determine market prices. The other options do not accurately capture this economic relationship.
If a fair six-sided die is rolled, what is the probability of rolling an even number?
3/4
2/3
1/2
1/6
A six-sided die has three even numbers (2, 4, and 6) out of six possible outcomes, which simplifies to a probability of 1/2. The other fractions do not represent the correct probability.
Solve the system of equations: 2x + 3y = 12 and x - y = 1.
x = 2, y = 3
x = 1, y = 2
x = 4, y = 1
x = 3, y = 2
By substituting x with y + 1 from the second equation into the first, we find that y = 2 and consequently x = 3. This solution satisfies both equations, unlike the other options.
A 10 kg object is on a frictionless incline at a 30° angle. What is the gravitational force component acting down the incline?
19.6 N
29.4 N
98 N
49 N
The gravitational component down the incline is calculated as mg sin(θ). With m = 10 kg, g = 9.8 m/s², and sin(30°) = 0.5, the force is 10 x 9.8 x 0.5 = 49 N. The other choices result from incorrect calculations.
In the reaction 2H2 + O2 â†' 2H2O, if you start with 5 moles of H2 and 3 moles of O2, which reactant is the limiting reagent?
Both reactants are in excess
Neither, they are in perfect ratio
H2
O2
The stoichiometric ratio for the reaction is 2 moles of H2 per 1 mole of O2. For 5 moles of H2, only 2.5 moles of O2 are needed, making H2 the limiting reagent as it will be exhausted first. The other options do not align with the reaction's stoichiometry.
Which event is widely recognized as the immediate trigger for World War I?
The assassination of Archduke Franz Ferdinand
The invasion of Poland
The signing of the Treaty of Versailles
The bombing of Pearl Harbor
The assassination of Archduke Franz Ferdinand in 1914 is commonly identified as the event that immediately triggered World War I. The other events are associated with different historical contexts or later time periods.
Which narrative perspective uses 'I' and often limits the story to the narrator's personal observations, sometimes making the narrator unreliable?
Third-person omniscient
Second-person narrative
First-person narrative
Third-person limited
A first-person narrative is told from the perspective of 'I', limiting the reader to one character's experiences and sometimes leading to an unreliable account. The other narrative styles provide different levels of perspective and insight.
