Answer:
I'm fairly certain that c=10. Don't quote me on that.
Step-by-step explanation:
Answer:
50 ft²
Step-by-step explanation:
If W is the width and L is the length, then:
L = W + 5
2L + 2W = 30
Solve the system of equations with substitution or elimination. Using substitution:
2(W + 5) + 2W = 30
2W + 10 + 2W = 30
4W = 20
W = 5
L = 10
The area of the rectangle is:
A = LW
A = 50 ft²
The answer to the question is D. It took me so long cuz' my phone died. *sry*
K= 4 because 8-4= 5. Therefore K= 4
