## Answers:

1- **E**

Simplify:

\(4(x + 1) = 6(x − 4) + 20\)

\(4x + 4 = 6x − 24 + 20\)

\(4x + 4 = 6x – 4\)

Subtract \(4x\) from both sides:

\(4 = 2x – 4\)

Add 4 to both sides:

\(8 = 2x\)

\(4 = x\)

2- **E**

\(2.5\%\) of \(1,200 = 0.025 × 1200 = 30\)

3-** E**

Use FOIL (First, Out, In, Last)

\((2x + 2y)(5x + 2y) = 10x^2+ 4xy + 10xy + 2y^2 = 10x^2+ 14xy + 4y^2\)

4- **E**

Use distributive property:

\(2x (4 + 2y) = 8x + 4xy = 4xy+ 8x\)

5- **E**

\(y = 4ab + 3b³\)

Plug in the values of a and b in the equation: \(a = 2 \)and \(b = 3\)

\(y = 4 (2) (3) + 3 (3)3 = 24 + 3(27) = 24 + 81 = 105\)

6- **C**

\(11 × 36 + 6 × 12 + 4 = 472\)

7- **D**

Let \(x\) be the integer. Then:

\(2x – 5 = 83\)

Add 5 both sides: \(2x = 88\)

Divide both sides by \(2: x = 44\)

8- **D**

To find the discount, multiply the number by \((100\% – rate of discount)\).

Therefore, for the first discount we get: \((200) (100\% – 15\%) = (200) (0.85) = 170\)

For the next \(15 \%\) discount: \((200) (0.85) (0.85)\)

9- **B**

Plug in each pair of number in the equation:

A. \((2, 1): 2 (2) + 4 (1) = 8\)

B. \((–1, 3): 2 (–1) + 4 (3) = 10\)

C. \((–2, 2): 2 (–2) + 4 (2) = 4\)

D. \((2, 2): 2 (2) + 4 (2) = 12\)

10- **E**

Use PEMDAS (order of operation):

\(5 + 8 × (–2) – [4 + 22 ×5] ÷ 6 = 5 + 8 × (–2) – [4 + 110] ÷ 6 = 5 + 8 × (–2) – [114] ÷ 6 = 5 + (–16) – 19 = 5 + (–16) – 19 = –11 – 19 = –30\)

11- **B**

Use this formula: Percent of Change

\(\frac{New \space Value-Old \space Value}{Old \space Value}× 100 \%\)

\(\frac{16000-20000}{20000}× 100 \% = 20 \%\)

and

\(\frac{12800-16000}{16000}× 100 \% = 20 \%\)

12- **D**

If the length of the box is 27, then the width of the box is one third of it, 9, and the height of the box is 3 (one third of the width). The volume of the box is:

\(V = lwh = (27) (9) (3) = 729\)

13- **D**

Write the equation and solve for B:

\(0.60 A = 0.20 B\), divide both sides by 0.20, then you will have \(0.60/0.20 A = B\), therefore:

\(B = 3\) A, and B is 3 times of A or it’s \(300\%\) of A.

14- **E**

To find the number of possible outfit combinations, multiply number of options for each factor:

\(6 × 3 × 5 = 90\)

15- **D**

The relationship among all sides of special right triangle

30\(^\circ\)-60\(^\circ\)- 90\(^\circ\) is provided in this triangle:

In this triangle, the opposite side of 30\(^\circ\) angle is half of the hypotenuse.

Draw the shape of this question:

The latter is the hypotenuse. Therefore, the latter is 60 ft

16- **E**

\(g(x)=-2, then f(g(x))= f(-2)=2 (-2)^3+5(-2)^2+2(-2)= -16+20-4=0\)

17- **E**

Let \(x\) be the width of the rectangle. Use Pythagorean Theorem:

\(a^2 + b^2 = c^2\)

\(x^2 + 8^2 = 10^2 ⇒ x^2 + 64 = 100 ⇒ x^2 = 100 – 64 = 36 ⇒ x = 6\)

Perimeter of the rectangle \(= 2 (length + width) = 2 (8 + 6) = 2 (14) = 28\)

18- **B**

The perimeter of the trapezoid is 36.

Therefore, the missing side (height) is \(= 36 – 8 – 12 – 6 = 10\)

Area of a trapezoid: \(A = \frac{1}{2}h (b_{1} + b_{2}) = \frac{1}{2} (10) (6 + 8) = 70\)

19- **B**

The probability of choosing a Hearts is \(13/52 = 1/4\)

20- **D**

Change the numbers to decimal and then compare.

\(\frac{2}{3}= 0.666…\)

0.68

\(67% = 0.67\)

\(\frac{4}{5} = 0.80\)
