Answer:
(x - 1) (x + 2) (x + 4)
Step-by-step explanation:
Factor the following:
x^3 + 5 x^2 + 2 x - 8
The possible rational roots of x^3 + 5 x^2 + 2 x - 8 are x = ± 1, x = ± 2, x = ± 4, x = ± 8. Of these, x = 1, x = -2 and x = -4 are roots. This gives x - 1, x + 2 and x + 4 as all factors:
Answer: (x - 1) (x + 2) (x + 4)
Step-by-step explanation:
The given quadratic equation is in standard form.
Answer:
c. 8 1/3 cups
Step-by-step explanation:
3 1/3 * 2 1/2 = 25/3 or 8 1/3
The formula for the area of a trapezoid is:
Substitute:
Simplify:
The area of the trapezoid is 104 cm.
b = i+12
b-3 = 4( i-3) ------> b-3=4i-12 ----->b=4i-9
b = i+12
b=4i-9
i+12=4i-9
21=3i
i=7
b= i+12
b=7+12=19 Ben is 19 years old now
