Study OutcomesCheat Sheet
Colorful paper art promoting a trivia quiz for Module Mastery 4 7, aimed at middle school math students.

Solve for x: x + 3 = 7.
x = 3
x = 10
x = 4
x = 7
To solve the equation, subtract 3 from both sides to isolate x. This results in x = 4, which is the only solution.
Which shape has three sides?
Rectangle
Triangle
Square
Pentagon
A triangle is a polygon with exactly three sides and three angles. The other options have four or more sides.
What is the value of 3 + 2 × 4?
11
20
14
9
Following the order of operations, multiplication is performed before addition. Thus, 2 × 4 equals 8, and adding 3 gives 11.
Simplify the fraction 4/8.
1/4
2/3
3/4
1/2
Both the numerator and denominator can be divided by 4, simplifying 4/8 to 1/2. This is the simplest form of the fraction.
What is the area of a rectangle with a length of 5 and a width of 3?
10
8
18
15
The area of a rectangle is calculated by multiplying its length and width. Multiplying 5 by 3 results in an area of 15.
Solve for x: 2x - 3 = x + 4.
x = 4
x = -7
x = 7
x = 1
Subtracting x from both sides yields x - 3 = 4. Adding 3 to both sides then gives x = 7, which is the correct solution.
Simplify the expression 2(3x + 4) - x.
5x + 4
7x + 4
5x + 8
6x + 4
Distribute 2 into the parentheses to get 6x + 8, then subtract x to obtain 5x + 8. This is the fully simplified form.
Factor the expression 4y + 12.
2(2y + 3)
y + 3
4(y + 3)
4(y + 12)
The greatest common factor in 4y and 12 is 4. Factoring out 4 gives 4(y + 3), which is the correct factored form.
What is the slope of the line passing through the points (1, 2) and (3, 8)?
6
3
4
2
The slope is calculated by dividing the change in y by the change in x: (8 - 2) / (3 - 1) = 6/2 = 3. This is the correct slope of the line.
Solve for x: 4/5 = x/10.
8
10
5
6
Cross-multiplying gives 4 × 10 = 5x, so 40 = 5x. Dividing both sides by 5 reveals that x = 8.
What is the sum of the roots of the quadratic equation x² - 5x + 6 = 0?
1
5
6
11
Vieta's formulas state that the sum of the roots of ax² + bx + c is -b/a. Here, -(-5)/1 equals 5, which is the sum of the roots.
What is the value of 2³?
6
4
9
8
2³ means multiplying 2 by itself three times: 2 × 2 × 2 equals 8. This is a basic exponentiation calculation.
In a triangle, two angles measure 50° and 60°. What is the measure of the third angle?
80°
70°
90°
60°
The sum of angles in a triangle is 180°. Adding 50° and 60° gives 110°, and subtracting this from 180° leaves 70° for the third angle.
Evaluate the expression 5(2x - 1) when x = 3.
15
30
20
25
Substitute x = 3 into the expression: 5(2(3) - 1) equals 5(6 - 1) = 5×5, which results in 25.
Solve for x: 3(x - 2) = 12.
10
4
6
8
Dividing both sides by 3 gives x - 2 = 4, and adding 2 to both sides results in x = 6. This is the correct solution.
Solve the system of equations: 2x + y = 10 and x - y = 1.
(5, 0)
(3, 4)
(11/3, 8/3)
(4, 2)
Substitute y = x - 1 (from the second equation) into the first equation to obtain 2x + (x - 1) = 10. Solving this results in x = 11/3 and y = 8/3.
If f(x) = 2x² - 3x + 1, what is the value of f(2)?
1
5
3
7
Substitute x = 2 into the function: 2(2²) - 3(2) + 1 equals 8 - 6 + 1, which simplifies to 3. This is the correct evaluation of f(2).
Simplify the expression (3x² - 12) / 3.
3(x² - 4)
3x² - 4
x² - 12
x² - 4
Divide both terms in the numerator by 3: 3x²/3 is x² and 12/3 is 4, leading to x² - 4. This is the simplest form of the expression.
What is the distance between the points (2, -1) and (-1, 3)?
5
√10
6
4
Using the distance formula, compute the differences: (-1 - 2) = -3 and (3 - (-1)) = 4. Thus, the distance is √((-3)² + 4²) = √(9 + 16) = √25 = 5.
Solve for x: 1/(x - 2) = 3.
5
3/7
7/3
2/3
Multiply both sides of the equation by (x - 2) to get 1 = 3(x - 2). Dividing by 3 gives x - 2 = 1/3, so x = 2 + 1/3 = 7/3. This is the valid solution.
