The answer is $30 cuz 5 x 6 is 30.
Step-by-step explanation:
The perimeter of a shape is the length around the edges. For a rectangle with length L and width W:
P = 2L + 2W
Given L = 2x + 3 and W = x – 2, we can substitute:
P = 2(2x + 3) + 2(x – 2)
P = 4x + 6 + 2x – 4
P = 6x + 2
7x + 3y = 30
-2x + 3y = 3....multiply by -1
-----------------
7x + 3y = 30
2x- 3y = -3 (result of multiplying by -1)
----------------add
9x = 27
x = 27/9
x = 3
7x + 3y = 30
7(3) + 3y = 30
21 + 3y = 30
3y = 30 - 21
3y = 9
y = 9/3
y = 3
solution is (3,3)
