## Best **TSI** Math Prep Resource for 2021

## Answers:

1- **D**

Use FOIL (First, Out, In, Last)

\((x + 7) (x + 5) = x^2 + 5x + 7x + 35 = x^2 + 12x + 35\)

2- **A**

\(\frac{54}{6}=\frac{27}{3}=9\)

\(\frac{48}{6}=\frac{24}{3}= 8\)

\(\frac{36}{6}=\frac{18}{3}=6\)

\(\frac{59}{6}=\frac{59}{6}\)

59 is prime number

3- **B**

\(x^2 – 81 = 0\) ⇒ \(x^2 = 81\) ⇒ \(x = 9\)

4- **C**

If \( a = 8\) then \(b =\frac{8^2}{4} + 4\) ⇒ \(b = \frac{64}{4} + 4\) ⇒ \(b = 16 + 4 = 20\)

5- **A**

If \(6.5 < x ≤ 9.0\), then x cannot be equal to 6.5

6- **A**

\(a=6\)⇒ area of triangle is \(=\frac{1}{2} (6×6)=\frac{36}{2}=18\) cm

7- **B**

Simplify:

\(10 – \frac{2}{3} x ≥ 12\) ⇒\( – \frac{2}{3}2 x ≥ 2\) ⇒ \(– x ≥ 3 ⇒ x ≤ – 3\)

8- **A**

Factor each trinomial \(x^2 – 2x – 8\) and \(x^2 – 6x + 8 \)

\(x^2 – 2x – 8\) ⇒ \((x – 4)(x + 2)\)

\(x^2 – 6x + 8\) ⇒ \((x – 2)(x – 4)\)

9- **B**

\(\frac{1+b}{6b^2}=\frac{1}{b^2}\)

⇒\((b≠0) b^2+b^3=6b^2\)⇒\(b^3-5b^2=0\)⇒\(b^2 (b-5)=0\)⇒\(b-5=0⇒b=5\)

10- **C**

\(53^\circ + 45^\circ = 98^\circ\)

\(180^\circ – 98^\circ = 82^\circ\)

The value of the third angle is \(82^\circ\).
