Solution
=8
Step-by-step explanation:
Represent the length and width by L and W. Then L = W + 4.
Using the perimeter formula: P = 2L + 2W = 68 ft = 2W) + 2(W+4).
Solve for W: 68 = 2W + 2W + 8, or 4W = 60. Thus, W = 15 and L = 19.
The dimensions of the rectangle are 15 by 19 feet.
The first property is commutative ( the numbers 38 and 677 are swapped over)
Then we have the associative property ( where the paretheses are moved to get 38 and -38 together)
then the additive inverse ( 38 + (-38) = 0
and finally to get the 677 we use the additive identity property.
8/25 is the answer. Hope this helps.
