Show work Perform the operations to simplify the expression:
(5x^5 + 4) - (2x^3+9)+(6x^5-x^3)

A. 11x^5+3x^3 + 5
B. 11x^5 - 3x^3 - 5
C. -3x^5 + 22x^3 + 5
D. 3x^5 + 11x^1 + 5

b.

Step-by-step explanation:

(5x^5 + 4) - (2x^3+9)+(6x^5-x^3)

5x^5 + 4 - 2x^3 - 9 + 6x^5 - x^3

5x^5 + 6x^5 = 11x^5

-2x^3 - x^3 = -3x^3

+4 -9 = -5

c is the correct answer

step-by-step explanation:

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base
