Answer:
400 pick mine as Brainlest
Step-by-step explanation:
BC is 21 meters.
2x + 5 + 3x = 45
5x + 5 = 45
5x = 40
X = 8
2(8) + 5 = BC
21 = BC

Usually, the "simplified" form has the polynomial multiplied out (as immediately above), rather than factored. If you want it factored, you can remove a factor of 7 from the terms of the numerator to get
7(x+1)/((x+2)(x-5)).
