Answer:
See below.
Step-by-step explanation:
If the original price is $p then final price is calculated as follows:
We start with p - 5 because the coupon was applied before the discount.
Final price = $( p - 5 ) - 0.2(p - 5)
= p - 5 - 0.2p + 1
= $(0.8p - 4).
4.0081 x 10 to the 4th power. I know because I did this one.
1/4(12 + x)
3 + 1/4x
The solution is 3 + 1/4x
Since one piece is four time the length <em>x, </em>we can represent that as 4x.
Thus making the equation:
4x+x=275
5x=275
x=55
4(55)=220
220+55=275
So, the length of the longer piece is 220 inches, and the length of the shorter piece is 55 inches.

<h2>A = 82.5 in²</h2>
Step-by-step explanation:
The formula of an area of a trapezoid:

b₁, b₂ - bases
h - height
We have b₁ = 10in, b₂ = 5in and h = 11in. Substitute:
