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
Answer:42
Step-by-step explanation:
the " l l " on the -14 cancel out the negative
In order to solve this problem easily you coin this method: Find the squares of 0.13 and 0.14. They are respectively 0.0169 and 0.0196. Irrational numbers are going to located between this interval, considering that we are not counting perfect squares.
are the three possible answers.
