## Best TSI Math Prep Resource for 2020

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 $$82^\circ$$.
