Option B.
5x−2)(4x^2−3x−2)
=(5x+−2)(4x^2+−3x+−2)
=(5x)(4x^2)+(5x)(−3x)+(5x)(−2)+(−2)(4x^2)+(−2)(−3x)+(−2)(−2)
=20x^3−15x^2−10x−8x^2+6x+4
=20x^3−23x^2−4x+4
Answer:
1
Step-by-step explanation:
A quarter is 25 cents. $4.17 + $0.25 = $4.42
She added 1 quarter.
We have 89 ounces of 47% iodine.
We will add "x" ounces of 14% iodine to get a 29% iodine solution.
89 * .47 + .14x = .29 * (89 + x)
41.83 + .14x = 25.81 + .29x
16.02 = .15x
x = 106.80
So, we must add 106.80 ounces of 14% iodine to get a 29% iodine solution.
(for a total of 195.80 ounces)

The answer is B.1/2 since it is just decreasing by half ever time u go back down
Answer:
x^6 y^3
Step-by-step explanation:
(x ^2 y)^3
We know that (ab)^c = a^c b^c
x^2^3 * y^3
We know that a^b^c = a^(b*c)
x^(2*3) y^3
x^6 y^3
