It is a quadratic expression and it is (7x+6)(7x+6) when factored
No, they do not.
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
Two equations: a linear one in y and a quadratic in x.
True because in both equations x = 0 or x = -4

9 squared is another way of stating the equation 9 X 9, and 10 squared is another way of stating the equation 10 X 10. Find the answers to these equations, add them together, and you will have the answer.
No
The solutions are: x = 4, y = 2 and x = -4, y = -2
6 squared plus 9 squared is equal to 117.
12 squared plus 18 squared is equal to 468.
25 squared plus 49 squared is equal to 3,026.
1 squared plus 8 squared or 4 squared plus 7 squared
