How do you factor y2 plus 14y plus 49?
(y + 7)(y + 7)
What is 25 squared plus 49 squared?
25 squared plus 49 squared is equal to 3,026.
Solve by substitution x plus 5y equal 10 and 7x minus 14y equal 49?
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
How do you work out 3 plus 4 3 plus 7 squared?
3 + 43 = 46 7 squared = 49 46 + 49 = 95

25 squared plus 49 squared is equal to 3,026.
What is the centre and radius of the circle x squared plus y squared plus 10x -14y plus 10 equals 0?
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
