Answer:

A. The value of x is 5

B. The length of each side is 20!

Step-by-step explanation:

For part A., We can determine x by setting these equations to equal each other (as we know that all sides of a square are equal)! See below for how to:

$4x = 2x +10\\2x = 10\\x=5$

For part B. sub x for 5 to get the side length of one side...

$4(5) = 20\\2(5) +10=20$

We already know that all sides are equal, so the side length of each side is 20!

What is the base (in inches) of a triangle with an area of 161 square inches and a height of 14 inches?

pantera1 [17]

$\textit{area of a triangle}\\\\ A=\cfrac{1}{2}bh ~~ \begin{cases} b=base\\ h=height\\[-0.5em] \hrulefill\\ h=14\\ A=161 \end{cases}\implies 161=\cfrac{1}{2}b(14) \\\\\\ 161=7b\implies \cfrac{161}{7}=b\implies 23=b$
