$\bf \textit{sum of all exterior angles in a polygon}\\\\ n\theta =360~~ \begin{cases} n=\textit{number of}\\ \qquad sides\\ \theta =angle~in\\ \qquad degrees\\[-0.5em] \hrulefill\\ n=15 \end{cases}\implies 15\theta =360\implies \theta =\cfrac{360}{15}\implies n=24$

PLEASE HELP For the expression below, write two other equivalent expressions using different terms. Make sure one is fully simpl

Julli [10]

Given:

The given expression is

$-4(x+2)-2x+4$

To find:

The two other equivalent expressions.

Solution:

We have,

$-4(x+2)-2x+4$

Using distributive property, we get

$=-4(x)-4(2)-2x+4$

$=-4x-8-2x+4$

So, one equivalent expression is $-4x-8-2x+4$ .

On further simplification, we get

$=(-4x-2x)+(-8+4)$

$=6x-4$

Therefore, the second and fully simplified equivalent expression is $6x-4$ .
