Which expression is equivalent to 7x+4X^2- 5x?

A 4x^2+ 10x

B 2x + 4x^2

C 2x - 4x^2

D 4X^2 - 2x

B

Step-by-step explanation:

Combine like term.

Hers 7x and (-5x) are like terms

7x + 4x² - 5x = 7x - 5x + 4x²

                    = 2x + 4x²

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
