## Answers:

1- **\(– x^2 – 3x – 6\)**

\((g – f)(x) = g(x) – f(x) = (– x^2 – 1 – 2x) – (5 + x) – x^2 – 1 – 2x – 5 – x = \ – x^2 – 3x – 6\)

2- **\(-38≤x≤32\)**

\(\frac{|3+x|}{7}≤5⇒|3+x|≤35⇒-35≤3+x≤35⇒-35-3≤x≤35-3⇒ -38≤x≤32 \)

3-** \(–\frac {\sqrt{3}}{3} \)**

\( tan (– \frac{π}{6}) = \ –\frac {\sqrt{3}}{3} \)

4- **\(4a^2\sqrt{b} \)**

\( \frac{\sqrt{32a^5 b^3}}{\sqrt{2ab^2} } = \frac{4a^2 \sqrt{2ab}}{b\sqrt{2a} } = 4a^2\sqrt{b} \)

5- **57,000 loss**

\(c(3)=(3)^2+10(3)+30=9+30+30=69 4×3=12⇒12-69=-57⇒57,000\) loss

6- **\(\frac{4}{5}\)**

sinB\(=\frac{Opposite Side}{Hypotenuse}=\frac{4}{5}\)

7- **\(y=\frac{6}{7} x+\frac{12}{7}\)**

\(-7y=-6x-12⇒y=\frac{-6}{-7} x-\frac{12}{-7}⇒y=\frac{6}{7} x+\frac{12}{7}\)

8- **\(0, -2, -3\)**

Frist factor the function:

\(x (x+2)(x+3)\)

To find the zeros, \(f(x)\) should be zero.

\(f(x)=x (x+2)(x+3)=0\)

Therefore, the zeros are:

\(x=0\)

\((x+2)=0 ⇒ x= -2\)

\((x+3)=0 ⇒ x= -3\)

9- **\((1,4)\)**

\(\begin{cases}5x+y=9\\10x-7y=-18\end{cases}\)⇒ Multiply the first equation by \(-2 ⇒ \begin{cases}-10x-2y=-18\\10x-7y=-18\end{cases}\) Add two equations \(⇒ –9y = –36 ⇒ y = 4\) then: \(x = 1\)

10- **4**

\((x – h)^2 + (y – k)^2 = r^2 ⇒\) center: (h,k) and radius: r

\((x – 3)^2 + (y + 6)^2 = 12 ⇒\) center: \((3,-6)\) and radius: \(\sqrt{16}=4\)
