Perimeter of a rectangle:
P = 2 L + 2 W, P = 72 ft
P ( new ) = 2* 3.5 L + 2 * 3.5 W = 3.5 * ( 2 L + 2 W ) = 3.5 P
P ( new ) = 3.5 * 72 = 252 ft
Answer:
The perimeter of the new rectangle is 252 ft.
Answer:
John did not make a mistake
Step-by-step explanation:
he did everything correct
Solving:
-7 + y = 3 + 2y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-2y' to each side of the equation.
-7 + y + -2y = 3 + 2y + -2y
Combine like terms: y + -2y = -1y
-7 + -1y = 3 + 2y + -2y
Combine like terms: 2y + -2y = 0
-7 + -1y = 3 + 0
-7 + -1y = 3
Add '7' to each side of the equation.
-7 + 7 + -1y = 3 + 7
Combine like terms: -7 + 7 = 0
0 + -1y = 3 + 7
-1y = 3 + 7
Combine like terms: 3 + 7 = 10
-1y = 10
Divide each side by '-1'.
y = -10
Hope it helps. (:
