Select the correct answer. Which expression is equivalent to this polynomial expression?
(2x^5+3y^4)(-4x^2+9y4)

-8x^ +18x^5y4 + -12x^2y^4 + 27y^8

Step-by-step explanation:

(2x^5+3y^4)(-4x^2+9y4)

= -8x^ +18x^5y4 + -12x^2y^4 + 27y^8

(2x^5+3y^4)(-4x^2+9y4) = -8x^ +18x^5y4 + -12x^2y^4 + 27y^8

The correct answer is B

x+y = 29, 5x + 2y = 100
