Answer:
13
Step-by-step explanation:
- x × (x + 9) = x² + 9x = 286
- x² + 9x - 286 = 0
- (x - 13)(x + 22)
- x = 13 or -22
- Since you cannot have negative length, it’s 13
Answer: Keisha can run faster than Stephan.
Step-by-step explanation:
Let's figure out how long it takes for them to run a mile.

It would take Stephan 5.25 minutes to run a mile

It would take Keisha 4.52 minutes to run a mile
Since Keisha takes less time to run a mile she is faster.
+5 on both sides
So you're left with 2x=33
Divide 2 from both sides
X= 16.5
150 is your correct answer
