I can help just tell me what model means I do not know I am in 5th grade
Answer:
x = 5
y = 3
Step-by-step explanation:
substitute x-2 for y in the other problem
X = 17-4(x-2) do your substituting and get x = 5
now you have x plug it into y = x-2
y = 5-2
y = 3
Answer:
Area = 16 in²
Step-by-step explanation:
Represent the length with L and the width with W
We have the following given parameters:
L = 4W
Perimeter = 20
Required
Determine the area.
The perimeter is calculated as thus:
Perimeter = 2(L + W)
Substitute 4W for L and 20 for Perimeter.
20 = 2(4W + W)
20 = 2 * 5W
20 = 10W
Solve for W
W = 20/10
W = 2
Recall that:
L = 4W
L = 4 * 2
L = 8
The area is then calculated as thus:
Area = L * W
Area = 8 * 2
Area = 16
Hence, the area is 16in²
