The answer is 80. This is because we can find the area of one of the triangles by (4*8)/2 = 16. We multiply this by 4 since there are 4 triangles. 16*4 = 64. Now finally, we add the area of the base to this value. 4*4+64=80. Therefore the answer is 80 cm^2
Answer:
Step-by-step explanation:
Bring the like terms together
5x + 22 - 6x -23 = 5x - 6x + 22 -23 {now, add/subtract the like terms}
= -x -1

Answer:
213 meters squared
Step-by-step explanation:
The surface area of a rectangular prism is found using the formula A=2(wl+hl+hw). Here substitute l = 6, w = 3.5 and h = 9.
A = 2((3.5*6) + (9*6) + (3.5*9))
A = 2(21 + 54 + 31.5)
A = 2(106.5)
A = 213
