Step-by-step explanation:
Answer:
378
Step-by-step explanation:
3*126
The curved surface area is equal to about 354.53
It would be half of the coefficient of x squared added to both sides:
So half of 8 ( the coefficient of 8x) is 4;
The number 4 squared is 16, so you would add that to both sides.
You do this so that you can easily factor the left side: x^2 + 8x + 16 = 4 + 16
(x + 4)(x+4) = 20
