Answer:
290 in²
Step-by-step explanation:
The surface area of a prism is found using the following formula: SA = 2(lh+lb+bh). This formula takes the area of each face (6 in total( and adds them together to find a total sum. Substitute l = 3, b = 8 and h = 11 to solve for the surface area.
SA = 2(lh+lb+bh)
SA = 2(3*11+3*8+8*11)
SA = 2(33 + 24 + 88)
SA = 2(145)
SA = 290
Answer:
no
Step-by-step explanation:
-7+x^2-3x = 9+x-10
-7+(-2)^2-3*(-2) 9+(-2)-10
-7+4+6 9-12
3 > -3
if we substitute -2 to x, answer is not equal
