Step-by-step explanation:

I think you need to do:

44(7x+12)(7x+12) = 180

44(49x²+178x+144) = 180

2156x²+7832x+6336= 180

and you finish and you find x

Solve for u. 15u − 12u = 15

Leno4ka [110]

15u - 12u = 5

First combine like terms

3u = 5

Then isolate the variable by dividing both sides by 3

u = 5/3

u = 1 2/3

Hope this helped!
