Add the polynomials. Assume all variable exponents represent whole numbers.(-6x7 - 5x5 + 13) + (9x7 - 16x5 - 6)

(-6x^7 - 5x^5 + 13) + (9x^7 - 16x^5 - 6) = 3x^7 - 21x^5 + 7

(-6x^7 - 5x^5 + 13) + (9x^7 - 16x^5 - 6)

= 3x^7 - 21x^5 + 7

= 3x^7 - 21x^5 + 7

This answer has been confirmed as correct and helpful.

Add the polynomials. Assume all variable exponents represent whole numbers. (-4x5 + 9x4 - 8x3 + 8) + (2x5 - 7x4 + 5x3 - 6)
**Weegy:**
(-4x^5 + 9x^4 - 8x^3 + 8) + (2x^5 - 7x^4 + 5x^3 - 6)
= -2x^5 + 2x^4 - 3x^3 + 2
