M + 2m + -4m = -5 What is m?

m = 5

Step-by-step explanation:

Rewrite problem

m + 2m + -4m = -5

Combine like terms

-1m = -5

Divide -1 on both sides

-1m = -5/-1

m = 5

Check answer

5 + 2(5) +-4(5) = -5

5+ 10 + -20

-5 = -5

Hope this helps :)

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
