Answer:
![x = \frac{380}{17}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B380%7D%7B17%7D)
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable
Hope this helps!
The answer is 9 if you plug them in
x2 - 12x = -6
Your next step would be to add 36 to both sides.
x2 - 12x + 36 = 30
In completing the square, we divide the term before x by 2, and then square it and add it to both sides.
12 / 2 = 6
6^2 = 36
That would be the next step.
Answer:
B
Step-by-step explanation:
Number A is wrong because 180-20-65 does not equal 90
Number B is right because x is equal to 180-90-65 which does not equal 90
We do not have to consider any more.
