7 or -8
72+7 = 56
(-8)2+(-8) = 56
You can solve this using some simple algebra.
Let x be the number you are looking for.
x2 +x-56-0
This can be factored as:
(x-7)(x+8)=0
Now use the zero property that says if AB=0, A=0 or B=0 (or both)
So x-7=0 and x=7 or
x+8=0 and x=-8

What is the area of the region x plus y squared equals 56 when x plus y equals 0?
If by area you mean X*Y it would be -49 (or 49, if you assume area to be positive). (X=7, Y=-7) when X+Y^2=56 and X+Y=0.
X squared plus y squared plus z if x equals 7 y equals 6 and z equals 4?

IF 2 plus 3 equals 10. 7 plus 2 equals 63. 6 plus 5 equals 66. 8 plus 4 equals 96 therefore 9 plus 7 equals?
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.

What equals 56?
56 can be expressed as the product of 7 and 8, as 7 multiplied by 8 equals 56. Additionally, 56 is the sum of 30 and 26, as 30 plus 26 equals 56. In terms of factors, 56 can be broken down into prime factors as 2 to the power of 3 multiplied by 7.
