Answer:
8
Step-by-step explanation:
9.6 divided by 3/4 = 0.8, so 8. Correct me if I'm wrong ya'll.
(x^2+3x^2-10x-24)/(x+2)
(4x^2-10x-24)/(x+2)
4x^2-10x-24=0
2x^2-5x-12=0
2x^2-5x-12/(x+2)
2x=(2x^2-5x)-(2x^2+4x)>>-9x-12
2x-9=(-9x-12)-(-9x-18)
2x-9=6
4x-18=12>>4x-6
(x-4)(2x+3) is the factorization
Answer:
−0.608761429
Step-by-step explanation:
use the pathagreom theorem if you have two sides subtract that from 180
check the picture below.
so, we know the dimensions of the pool, is a 20x10, so its area is simply 200 ft², and we know the walkway is 216 ft², so the whole thing, including pool and walkway is really 200 + 216 ft².
now, as you see in the picture, the dimensions for the combined area is 20+2x and 10+2x, since the walkway is "x" long, therefore,

notice, it cannot be -18, since is a positive length unit.
(5x)^2 + x^2 = c^2
25x^2 + x^2 =c^2
sqrt 26 x ^ 2 = sqrt c^2
x sqrt 26= c
so answer is 6x + x sqrt 26
