Answer:
22 feet
Step-by-step explanation:
width = x
length = 4 + 3x
Perimeter = 2(4+3x) + 2x
8+6x+2x =56
8x =48
x=6
4+3x=4+3times6=22 --> lenght
Answer:
the first one is a function! there are no repeated x values in a function
Answer:
Yes, that is correct.
Step-by-step explanation:
W = x
L = ?
A = x^2 + 12x
(x^2 + 12x)/x = x + 12
L = x + 12
Subbing in 10 for each X, we get:
Perimeter: 64
2(10) + 2(10 + 12) = 20 + 44 = 64
Area: 220
10 * 22 = 220
