First think of the form a^2 + 2c + c^2
c in the question is clearly 3.
So we need first to add 8 for both sides to get rid of -8 and then add 9 to complete the square.
So it will be (x^2+3)^2 = 17
So the choice number 3 is the answer.
Hope this helps!
The letter A is equivalent
0.5•175=87.5 This is you answer, do you understand?
Y = 49 degrees. 29 + 102 = 131 and every triangle has an angle sum of 180. 180 - 131 = 49.
