<u>Answer:</u>
2
<u>Step-by-step explanation:</u>
In order to solve a system using the additional method, we would need to multiply the first equation by '2' in order for the x’s to add out.
We have the following equations:
--- (1)
--- (2)
We will multiply equation (1) by 2 and equation (2) by 3 to cancel the x's.
Answer:
Length= 24 feet
Width= 16 feet
Step-by-step explanation:
Equation 1) Perimeter = 2L+2W
Equation 2) Perimeter = 80
Equation 3) L-8=W
1) Substitute L-8 as W in the first equation, and 80 as the Perimeter:
2L+2(L-8)=80
2) Distribute 2 to L and -8:
2L+2L-16=80
3) Add 16 to both sides, and combine alike terms:
4L=96
4) Divide both sides by 4:
L=24
5) Substitute 24 as L in the third equation:
24-8=W
6) Solve:
W=16
