Hi can someone me: ) and it’s units^2

answer:

42units^2

step-by-step explanation:

use the image to visualize the problem here (sorry for bad handwriting). you would make the shape into a rectangle and solve as normal. the length would be 12 while the width would be 7 (the 6 and 1 added together on top. 12*7= 84. afterwards you would want to divide 84 by 2 since the shape is half of the rectangle itself therefore you would get 84/2=42.

Three times = 3x

Decreased by five = -5

So: 3x - 5 = 13

You can solve for this by doing:

3x = 13 + 5

3x = 18

x = 6
