What is the product? (y^2)(2x^3+5)(x^2-4x-9)

2x5y2−8x4y2−18x3y2+5x2y2−20xy2−45y2

Step-by-step explanation:

y2(2x3+5)(x2−4x−9)

=(y2(2x3+5))(x2+−4x+−9)

=(y2(2x3+5))(x2)+(y2(2x3+5))(−4x)+(y2(2x3+5))(−9)

=2x5y2+5x2y2−8x4y2−20xy2−18x3y2−45y2

=2x5y2−8x4y2−18x3y2+5x2y2−20xy2−45y2

If this is not it, I don't know what is.

Hope this helps! :)

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
