The perimeter of a rectangle = 2(l + w)
l = length
w = width
In this problem,
w = x
l = x + 30
the perimeter = 148
Let's plug our values into the perimeter formula above.
148ft = 2(x + x + 30ft)
Combine like terms.
148ft = 2(2x + 30ft)
Distribute the 2
148ft = 4x + 60
Subtract 60 from both sides
88ft = 4x
Divide both sides by 4
22ft = x
The width = x = 22ft
The length = x + 30 = 22 + 30 = 52ft
D. AH
Segment AH is parallel to BD and if the lines were drawn out infinitely, the two lines would never meet.
He will have 7.75 left from the 20 dollar bill he spent
58.51%
however, it is estimating so depending on the answer choices it would be around 55-60% or so
