Answer:
(x-7) (x^2-5)
Step-by-step explanation:
x^3-7x^2-5x+35
Factor out an x^2 from the first two terms and -5 from the last 2 terms
x^2 (x-7) -5(x-7)
Factor out (x-7)
(x - 7) (x^2 - 5)
Factor the following:
x^3 - 7 x^2 - 5 x + 35
Factor terms by grouping. x^3 - 7 x^2 - 5 x + 35 = (x^3 - 7 x^2) + (35 - 5 x) = x^2 (x - 7) - 5 (x - 7):
x^2 (x - 7) - 5 (x - 7)
Factor x - 7 from x^2 (x - 7) - 5 (x - 7):
Answer: (x - 7) (x^2 - 5)

Answer:confusing
F. 4h ≥ 18
Liang wants ...
distance ≥ goal
We know that ...
distance = speed · time . . . . . . where speed = 4 mph, and time = h hours
Then the appropriate inequality for Liang's goal of 18 miles or more is ...
4h ≥ 18
