The perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is 2l + 2w=16, where l re
cricket20 [7]
2l + 2w = 16   
2(l+ w)  = 16    Divide both sides by 2
l + w =  16/2

l + w  =  8

So for example the length l could be 5 and the width could be 3.
Length could be 5.

PLEASE HELP ME
Mamont248 [21]

Answer:

Reflection in the x-axis followed by a translation 5 units left and 1 unit up

Step-by-step explanation:

The coordinates of X are (-6,2).

When we reflect in the x-axis we get X'=(-6,-2)

When we translate by the rule T(x-5,y+1), we get X"=(-6-5,-2+1)=(-11,-1)

The coordinates of Y are (-4,7).

When we reflect in the x-axis we get Y'=(-4,-7)

When we translate by the rule T(x-5,y+1), we get Y"=(-4-5,-7+1)=(-9,-6)

The coordinates of Z are (-2,2).

When we reflect in the x-axis we get Z'=(-2,-2)

When we translate by the rule T(x-5,y+1), we get Z"=(-2-5,-2+1)=(-7,-1)

Therefore the sequence of transformation is a reflection in the x-axis followed by a translation 5 units left and 1 unit up.
