Well we know that the perimeters are equal so:
Psquare = Prectangle
we know perimeter for square is the 4 sides of same lengths added up or 4*s
the perimeter of a rectangle is the then4 sides with 2 being equal added up so 2*L + 2*W
we know that a square side equAls s and it says that s=8x. So:
Psqu = 4 * (8x) (substitute 8x for s)
we know that the rectangle L =10x + 8 and W =10. So
Prect = 2 *(10x + 8) + 2 * (10)
we know :
Prect = Psqu so:
4 * (8x) =2 *(10x + 8) + 2 * (10)
32x = 20x + 16 + 20
12x = 36
x = 3
So if x equals 3 we can sub x in for square perimeter
Psqu = 4 *(8 * 3)
P = 4 * 24
P = 96
we can check this with rectangle perimeter
P = 2 *(10 * 3 + 8) + 2 *10
P = 2 * 38 + 20
P = 96
5, because the spouse can be an exemption if not claimed as a dependent on another person's return. The head of household is an exemption as the person doing the return and all kids.

Answer:
Step-by-step explanation:
We need x first.
AB = DE
12 = 3x -3
4 = x -1 . . . . . divide by 3
5 = x
Now, we can find y.
∠C = ∠F
7x +y = 55
y = 55 -7x = 55 -7(5)
y = 20
Answer:
19 or m = 19
Step-by-step explanation:
7(13) - 4(13) = m + 20
91 - 52 = m + 20
39 = m + 20
subtract 20 from both sides to get m = 19
