Look at the following numbers:

− 4, −1, 0, 4

Which pair of numbers has a sum of 0?

What is the value of the expression "two less than six times the diffrence of a number and five" when n = 9?

What is the value of x in the equation 6(x + 1) – 5x = 8 + 2(x – 1)?

Kylie explained that (-4x+9)^2 will result in a difference of squares because (-4x+9)^2 (-4x+9)^2 =(-4x)^2+(9)^2=16x^2+81
