9r2-4s2/9r+6sIt looks like you can factors the numerator(3r + 2s)(3r - 2s) [This is the factored form of 9r2-4s2]Put this back into the equation(3r+2s)(3r-2s)/9r+6sYou can also factor the denominator3(3r+2s)Put this back into the equation(3r+2s)(3r-2s)/3(3r+2s)You can cancel out the 3r+2s on top and bottom because they are the same they equal 1. Therefore your final answer is3r-2s over 3You could go further and say this is...r-(2/3)seither one is correct
They are: y, r, s, z and m which makes 5 of them
-7p + 5r - 6p + 3r = -7p - 6p + 5r + 3r = -(7 + 6)p + (5 + 3)r = -13p + 8r
It is not correct to say that 8 plus 2 8r-2r 4 3r plus 2 r = 0
9r = 3r+6 Subtract 3r from both sides: 6r = 6 Divide both sides by 6 to find the value of r: r = 1

-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r
(3r + 2)(r - 5)
If: -5 = 7+3r then the value of r works out as -4
They are: y, r, s, z and m which makes 5 of them
It is (7 + a)r.
-7p + 5r - 6p + 3r = -7p - 6p + 5r + 3r = -(7 + 6)p + (5 + 3)r = -13p + 8r
It is not correct to say that 8 plus 2 8r-2r 4 3r plus 2 r = 0
9r = 3r+6 Subtract 3r from both sides: 6r = 6 Divide both sides by 6 to find the value of r: r = 1
9r = 3r + 6 subtract 3r from both sides 6r = 6 divide both sides by 6 r=1 ■
