1 is 4a+15b
2 is 5x-4
3 is 2x-22
4 is 8x-21
5 is 25x + 55
6 is 55x - 17
Answer:
x^2 - 3x - 40
Step-by-step explanation:
x = 8 and x = -5
x - 8 = 0 and x + 5 = 0
(x - 8)(x + 5)
x^2 + 5x - 8x - 40
x^2 - 3x - 40
Answer: x^2 - 3x - 40

He can run 112 yards in 12 seconds
Step-by-step explanation:
Here, we want to know the number of yards he can run in 12 seconds

So the number of yards he can run in 12 seconds will be;
38 * 12/4
= 38 * 3 = 114 yards
8368 is 10 more than 8358
