Answer:(4)
Step-by-step explanation:
1/2=x/8 cross multiply and you come up with 8 divided by 2 = 4
Answer:
4 x 4 = 16, 16 divided by 2 ( x 1/2 ) = 8
8 x 2 = 16(area of two triangles)
8 x 4 = 32(area of base below)
5.7 x 8 = 45.6 (area of slant)
4 x 8 = 32(area of the rectangle behind the figure)
Add all the given areas:
16 + 32 + 45.6 + 32 = 125.6 in^2 is your answer

that's one combination for f(x) and g(x), off many combinations.
