Hi there! :)
Answer:
5n + 6 = -3n - 10
Solve for n:
Add 3n to both sides:
5n + 3n + 6 = -3n + 3n - 10
8n + 6 = -10
Subtract 6 from both sides:
8n + 6 - 6 = -10 - 6
8n = -16
Divide both sides by 8:
8n/8 = -16/8
n = -2.
The base's length is 8 and it's width is 7, so it's perimeter will be 
. To find the lateral area you shoul multiply this with it's height. So, 
(h is height).
