Which is a factor of x^2 + 8x - 48?
(х – 6)
(х + 4)
(х – 16)
(х + 12).

Answer

(x+12)

Explanation

When your checking a factor, the sign is the opposite, so you would plug in -12 to try (x+12). -12^2 +8(-12)-48.

Then solve:

-144+144=0

(x+12) is your answer.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
