(3x^2 + 5x + 2) + (5x^2 – 3x - 7)
= 3x^2 + 5x + 2 + 5x^2 – 3x - 7
= 8x^2 + 2x - 5

Multiply this polynomial: (6x^2y^4)(- 5x^3y)
Weegy: 2(2x/3 + 7) - 3 = 5x 4x/3 + 14 - 3 = 5x 11 = 11x/3 x = 3 y = 2(3)/3 + 7 = 9 x(y) = 3(9) = 18. Answer is d. (More)

Using F.O.I.L, multiply: (3x^2 + 5) (3x^2- 5)
Weegy: (3x^2 + 5) (3x^2- 5) = 9x^4 + 15x^2 - 15x^2 - 25 = 9x^4 - 25 (More)
