Answer:
2x + 1/2 sq. ft
Step-by-step explanation:
Surface area = 2(lw+wh+lh)
Given
length l = x ft
width w = 1/2 ft
height h = 1/2ft
Substitute
Surface area = 2(x(1/2)+(1/2)(1/2)+x(1/2))
Surface area = 2(x/2+1/4+x/2)
Surface area = 2(2x/2 + 1/4)
Surface area = 2(x + 1/4)
Surface area = 2x + 2/4
Surface area = 2x + 1/2 sq. ft
Answer: 5(x-1)
Step-by-step explanation:you combine like terms which is "X" and "4x" will give you (5x-5). then you factor out the 5 and that will give you 5(x-1)
5=54 because 3x4= 12 + 6x7=42
I am not 100% sure but I believe 6=11.8
9=37 because 7x3=21 + 2x8=16
