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
The answer to the first question is D.)
The 6 in front of the parentheses modifies both 'x' and 3
The answer to the second question is D.)
When you plug 4 into the equation, you get 14
3(4) + 2 = 14
12 + 2 = 14
14=14
