Answer:
2/(x+7)
Step-by-step explanation:
x²+5x-14 factors as (x-2)(x+7)
SO - multiply the fraction on the right by x+7 (both top and bottom)
Then both have the same denominator (x-2)(x+7), and the 1 becomes x+7.
Then you combine the fractions to make ((3x+3)-(x+7))/(x-2)(x+7).
This becomes (2x-4)/(x-2)(x+7).
You can factor the 2 out of the numerator for 2(x-2).
You now have 2(x-2)/(x-2)(x+7)
The (x-2)’s cancel out and you are left with
2/(x+7)

<em>Hey there!</em>
Well if the length is 18 and 3 inches we need to find the sum of both lengths,
18ft 3in + 18ft 3in = 36ft 6in
Width- 10ft 8in + 10ft 8in = 20ft 16 in -> 21ft 4in
l + w = 57ft 10in
