Ineed with 11,12,15,16 and this is distributive property with parenthesis show steps i have to do a out of state college tour so yea

11. 2(x-5+2) = 6

    2x-10+4=6

    2x-6=6

    x=6

With that you should be able to understand. Make sure you show your work for your teacher!

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

it'll be: x^2=36

x=6,x=-6
