(x - 13y)(x + 13y)
Eqn 1: x - 2y = 3 Eqn 2: 5x + 3y = 2 5 times Eqn 1: 5x - 10y = 15 Eqn 2 - 5*Eqn 1: 0x + 13y = -13 so that 13y = -13 or y = -1 Substitute in Eqn 1: x + 2*1 = 3 x + 2 = 3 x = 1 Solution: x = 1, y = -1
If y2 + 13y = 40, then y ~ 15.55If y2 + 13y = 0, then y = -13Improved Answer:-y2+13y+40 = 0(y+5)(y+8) = 0Therefore: y = -5 and y = -8
-26x
(y2+13y+22)/(y+2) = (y+11)
3x - 8y + 2x - 5 - 5y = 5x -13y - 5
(x - 13y)(x + 13y)
Eqn 1: x - 2y = 3 Eqn 2: 5x + 3y = 2 5 times Eqn 1: 5x - 10y = 15 Eqn 2 - 5*Eqn 1: 0x + 13y = -13 so that 13y = -13 or y = -1 Substitute in Eqn 1: x + 2*1 = 3 x + 2 = 3 x = 1 Solution: x = 1, y = -1
9x - 3(x + 13y) = 9x - 3x - 39y = 6x - 39y = 3(2x - 13y)
-2x+13y=11 13y=2x+11 y=2x/13 + 11/13
If y2 + 13y = 40, then y ~ 15.55If y2 + 13y = 0, then y = -13Improved Answer:-y2+13y+40 = 0(y+5)(y+8) = 0Therefore: y = -5 and y = -8

42+4y -12 = 13y -12 -2y 4y -13y+2y = 12 -12 -42 -7y = -42 y = 6
(y2+13y+22)/(y+2) = (y+11)
y= -3/13​​
If you mean: 4y^2 +3 -13y then the expression is (4y-1)(y-3) when factored
Yes, if its for a kid you can make it under 13y/o so they can only say certain things, 13y/o and up you can type whatever but only to other 13y/o and still some words are banned.. Some people make inappropriate clothing.. Only a few. I have only seen 1.
