Give two reasons why this shape is a square when x=5.

First of all, we can see that this shape have 4 90° angles.

Secondly, since x = 5 we have:

  3 × 5 -2 = 15 - 2 = 13 (cm)

And: 5 + 8 = 13 (cm)

=> The two adjacent sides that make up the angle is equal to each other

So this shape is a quare.

=> This shape is a square.

y=mx+b is the final answer!   : )

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
