Answer:
HTP
Step-by-step explanation:
If (ax + 2)(bx + 7) = 15x² + cx + 14 for all values of. X, and (a + b = 8. what are the two possible values ... A landscaping company estimates the price of a job, in dollars ... and h is the total number of hours the job will take ... DI Each landscaper works 12 hours a day. no h ... no more than 20 hours per week, but she wants to
Get into ax²+bx+c=0 form
subsitute u=x⁴
x⁸-3x⁴+2=0
(x⁴)²-3(x⁴)+2=0
u²-3u+2=0
factor
(u-2)(u-1)=0
set to zero
u-2=0
u=2
u-1=0
u=1
wait, u=x⁴
2=x⁴
![\sqrt[4]{2}=x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2%7D%3Dx)
1=x⁴
+/-1=x
the subsitution is u=x⁴
and the possible values for x are -1,
![\sqrt[4]{2}=x](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2%7D%3Dx)
, and 1

Find f(-5) by substituting x = -5 in the equation.

Therefore, the answer is f(-5) = 16
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.
