What is the answer to 9a-3(2a-4)=15
Alecsey [184]

Answer:

a=1

Step-by-step explanation:

The answer to this problem is 1. This is the answer because  using PEMDAS, you would first have to distribute -3.

So: 9a+ -6a+12=15

Combine like terms:

3a+12=15

Subtract 12 on each side. 3a= 3

Divide 3 on each side.

a=1

Hope this helps!! :D

So it would be:
x = 8

Lina20 [59]

Answer:

love youre profile it's from Saiki K

Step-by-step explanation:

We use the factoring form becuase our c is zero and it in standard quadratic form so we rather factor than complete the square or quadratic formula since that is longer to do than just factor.
