CXC Test Practice Quiz

Using the order of operations, multiplication is performed before addition. Therefore, 2 * 5 is 10, which when added to 3 gives 13.

7 raised to the power of 2 means 7 multiplied by 7, which results in 49. This basic exponentiation reinforces quick arithmetic skills.

The verb in a sentence describes an action. In this sentence, 'barks' is the action performed by the dog.

The correct punctuation uses an apostrophe in 'can't'. Proper punctuation is essential for clear communication and correct grammar.

The perimeter of a rectangle is calculated by adding twice the length and twice the width, which is 2*(5 + 3) = 16. This reinforces understanding of basic geometric formulas.

Subtracting 3 from both sides gives 2x = 8, and then dividing by 2 yields x = 4. This is a straightforward linear equation.

By substituting x = 4 into the function, we get f(4) = 3(4) + 2 = 12 + 2 = 14. This reinforces the concept of function evaluation.

Rewriting the equation in slope-intercept form gives 2y = 4x + 8, or y = 2x + 4. Therefore, the slope is 2, demonstrating how to rearrange equations to identify slope.

A semicolon is used to join two closely related independent clauses without a conjunction. Option 2 correctly demonstrates this punctuation rule.

The word 'rapid' means fast, so its antonym is 'slow'. This question tests knowledge of vocabulary and opposites.

The area of a triangle is calculated using the formula ½ * base * height. So, ½ * 6 * 4 gives an area of 12.

Prepositions are words that show the relationship between other words in a sentence. 'Through' is the word that indicates this relationship in the sentence.

First, distribute 5 to get 10x - 15, then add 10 to obtain 10x - 5. This uses the distributive property to simplify the expression.

A sentence is in the passive voice when the subject receives the action rather than performing it. Option 2 is structured in such a way that the focus is on the action being performed on the lesson.

A simile directly compares two different things using 'as' or 'like'. The sentence 'Her smile was as bright as the sun' uses 'as' to make this comparison, making it a clear example of a simile.

Situational irony occurs when the outcome of a situation is the opposite of what is expected. The example of a firefighter's house burning down is a classic instance of situational irony.

A quadratic equation has exactly one real solution when its discriminant is zero. For the equation x² - 4x + k = 0, setting the discriminant (16 - 4k) to zero gives k = 4.

Alliteration is the rhetorical device that features the repetition of the same initial consonant sounds across successive words. This technique is often used in poetry and prose to enhance rhythm and mood.

The expression can be factored as (x - 2)(x + 2) over (x - 2). Canceling the (x - 2) terms for x ≠ 2 leaves x + 2. Substituting x = 2 gives 4.

A theme in literature represents the underlying central idea or message that the author intends to convey. It is not merely a character trait or the sequence of events but a broader insight into life or society.
