Answer: uhhh
Step-by-step explanation:
3+1=4, 4+2=6, 6+3=9, 9+4=13, 13+5=18, 18+6=24, 24+7=31. Your answer is 31. Each time , the number you add by is increased by 1
7x + 5 = 5x + 11
2x + 5 = 11
2x = 6
x = 3
7(3) + 5
21 + 5 = 26
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!
