Answer:
A. -8x⁷ + 18x⁵y⁵ - 12x²y⁴ + 27y⁸
Step-by-step explanation:
Given:
(2x⁵ + 3y⁴)(-4x² + 9y⁴)
Required:
Find an equivalent polynomial
Solution:
(2x⁵ + 3y⁴)(-4x² + 9y⁴)
Using distributive property of multiplication
2x⁵(-4x² + 9y⁴) + 3y⁴(-4x² + 9y⁴)
-8x⁷ + 18x⁵y⁴ - 12x²y⁴ + 27y⁸
There are no like terms to add or combine, therefore:
(2x⁵ + 3y⁴)(-4x² + 9y⁴) = -8x⁷ + 18x⁵y⁵ - 12x²y⁴ + 27y⁸
42 divided by 40 = 1.05 = 105%. Hope I helped!
(-4, -8), because it gives you X(-4) so you just substitute X in the first equation with -4 so y=1/2(-4)-6. And the. You solve for y. 1/2(-4)=-2, -2-6=-8 so y=-8. So then you put it into (x,y) form so that would be (-4, -8). Hope this helps! :)
