Question

U have to just say the answers. Because my teacher said this is a timed homework getting us getting for a big state test.

Answer 1

Given:-

$\begin{gathered} (-3)(-1)(-5)=_{} \\ -6(-2-1)-2(-8+6)= \\ \frac{\frac{2}{7}}{\frac{2}{7}}= \\ \frac{3-\lbrack(5-7)-4\rbrack}{-2-4-3}= \\ 4(2x+1)= \end{gathered}$

To find:-

The simplified form.

So now we simplify,

$\begin{gathered} (-3)(-1)(-5)=(3)(-5)=-15 \\ -6(-2-1)-2(-8+6)=-6(-3)-2(-2)=18+4=22 \\ \frac{\frac{2}{7}}{\frac{2}{7}}=1 \\ \frac{3-\lbrack(5-7)-4\rbrack}{-2-4-3}=\frac{3-\lbrack-2-4\rbrack}{-6-3}=\frac{3-(-6)}{-9}=\frac{9}{-9}=-1 \\ 4(2x+1)=8x+4 \end{gathered}$

These are the required solutions.
