Answer:
(x + 8) (x² - 3)
Step-by-step explanation:
Given:
x³ + 8x² - 3x - 24
Find:
Factors
Computation:
x³ + 8x² - 3x - 24
x²(x + 8) -3(x + 8)
(x + 8) (x² - 3)
Factor of the given equation is (x + 8) (x² - 3)
(10x + 4) + (5x-4) ≈ 180
solve for x and you get x≈12
plug 12 in to 5x-4 and you get 56

Paul ran a 26 1/5 mile marathon in 2 3/4 hours
<u>Paul's average speed was:</u>
- distance/time =
- 26 1/5 : 2 3/4 =
- 131/5 : 11/4 =
- 131/5 * 4/11 =
- 524/55 =
- 9 29/55 mph
<u>Inequality for the speed of faster runners:</u>
