2x+2x+60=180 because the angles have to add up to 180
So you have
4x+60=180
4x=120
x=30
Answer:
16
Step-by-step explanation:
If P=2b +2s then you plug in the variables
The answer would be A because if you combine all the like terms you will get A as a result.
-2x^2+8x-9+4x+7x^2+2
-2x^2+7x^2 combine both of these and it will get you 5x^2
And then you would do 8x+4x which would be 12x and lastly you would -9+2 which would be -7 so the answer is A.
Hope this helps!!
A is 6 for the intercept.
