(y + 7)(y + 7)

25 squared plus 49 squared is equal to 3,026.

set it up as x+5y=10 and 7x-14y=49 on top of each other and then multiply x+5y=10 by -7. That gives you -7x-35y=-70. cross out the X's and add the Y's. -21y=21 divide and get -1=y then sub. for x and solve. X=15 and X=5

3 + 43 = 46 7 squared = 49 46 + 49 = 95

x=7

25 squared plus 49 squared is equal to 3,026.

Equation: x^2 + y^2 +10x -14y +10 = 0 Completing the squares: (x+5)^2 + (y-7) -25-49 +10 = 0 So: (x+5)^2 + (y-7) = 64 Therfore the circle's centre is at (-5, 7) and its radius is 8

9t2 + 42t + 49 is a perfect square, equal to (3t + 7)2

They are equal. 7 squared is 7 x 7, which equals 49. 6 x 7 = 42, plus another 7 = 49.

72 = 49.72 + t = 49 + t

(9x2 + 7)(9x2 - 7) = 81x4 - 49
