Answer:
2 B + p h
Step-by-step explanation:
The Surface Area = 2 B + p h
B is the area of the triangular base of prism
p perimeter of the base and
h the height of the prism
C
x = - 36
multiply both sides of the equation by - 2
x = (- 2)× 18 = - 36
no solution I believe
b/c x and y cancel out so it cant be solved
