7 Or -8
7
X^2 + x = 56 ie x(x +1) = 56 so x is 7
72 + 7 = 56
The answer is 7. Seven squared is forty nine. 49 plus 7 equals 56.
65
35 squared = 35 x 35 = 1225 56 squared = 56 x 56 = 3136
No. Square numbers are numbers formed when a number is multiplied by itself. So 2 squared is 2 times 2, which is 4. 3 squared is 3 times 3 which is 9. 4*4=16 5*5=25 6*6=36 7*7=49 8*8=64

By "squared", I'm certain you mean the 562, correct? If that's what you mean, then the answer to that is 75,264. The small 2 means that you multiply that number by itself, so 56x 56=3136, and 3136 x 24=75,264.
56
Yes it is.
