A. 4*4-4-4=16-4-4=12-4=8 true
B. 4*4*4-4=16*4-4=64-4=60, not 8 false
C. 4*4+4-4=16+0=16, not 8, incorect
D. 4(4+4)-4=4(8)-4=32-4=28, not 8 incorrect
A
Answer:
5
Step-by-step explanation:
f(x) = 2x - 3x + 7
Plug in 2 every time you see an x within the equation: x = 2
f(2) = 2(2) - 3(2) + 7
f(2) = 4 - 6 + 7
f(2) = -2 + 7
f(2) = 5
Area = Length * Width
A = 1/2 * 3/4
A = 3/8
In short, Your Answer would be 3/8 Ft^2
Hope this helps!
