Answer:
( k-4)(k+2)
Step-by-step explanation:
k² - 2k - 8
What 2 numbers multiply to -8 and add tp -2
-4*2 = -8
-4+2 = -2
( k-4)(k+2)
Answer:
x = 6
Step-by-step explanation:
2/(x-2) = 5/(4+x) - set up the ratios of similar sides
2(4 + x) = 5(x - 2) - cross multiply to solve
8 + 2x = 5x - 10 - simplify
18 = 3x - simplify to get x on one side of the equation
6 = x - divide both sides of the equation by 3 to isolate x
Answer:
yes, the answer is b = -15
Step-by-step explanation:
3(-15) = -45
-45 + 9 = -36
-36 - 16 = -52
so b = -15
Well i graph each one of those and the first choice seems to be correct.
