One side of a rectangle is 6 yd longer than three times another side. The area of the rectangle is 72 yd2. Find the length of th
TiliK225 [7]

Answer:

18 yds

Step-by-step explanation:

Let the length and width be L and W respectively.

Then L· W = area = 72 yd², so that L = (72 yd²) / W.

But also L = 3W + 6 yd.  Subbing this into  L· W = area = 72 yd², we get:

(3W + 6) · W = 72, or

3W² + 6W - 72 = 0.  Since all  four terms are evenly divisible by 3, we get:

W² + 2W - 24 = 0, which factors as follows:

(W + 6)(W - 4) = 0.  Then W + 6 = 0, or W = -6 (makes no sense for a length), and W - 4 = 0 yields W = 4 yds.

If the shorter side is of length 4 yds, then the longer side is of length

L = 3(4 yds) + 6 yds = 18 yds

L'oreal car travels 420 miles on a full tank of gas her tank can hold 14 gallons. laila car can travel 435 miles on 15 gallons.
Kisachek [45]
L’oreal’s car can gets better mileage because you have to divide both the miles and the amount of gallons they carried. L’oreal: 420 divided by 14 is 30 = 30 miles per gallon. Laila: 435 divided by 15 = 29 miles per gallon. But since we have to even out the amount of gallons they both carry, we can either take away 29 to the 435 (Laila), or add 30 to the 420(L’oreal). 420 + 30 = 450. 435 - 29 = 406. 420 > 406 = 450 > 435. L’oreal has the better mileage
