Solving for the Positive Absolute Value:

Solving for the Negative Absolute Value:

If you would like to find the value of a in the polynomial, you can do this using the following steps:
(y - 4)(y^2 + 4y + 16) = y^3 + 4y^2 + 16y - 4y^2 - 16y - 64 = y^3 + 4y^2 + ay - 4y^2 - ay - 64
a = 16
The correct result would be 16.
Well since two solid numbers cant make 7 I would do 3.5 x 7
Answer:
$1.81
Step-by-step explanation:
10 - 8.19 = 1.81
Since this is a percentage, all you have to do is divide 21 from 80 and multiply that by 100
21/80 = .2625 * 100 is 26.25
The answer closest to this is 25%, so the answer is 25%
Hope this helped! :D
