What is 9r squared-4s square over 9r plus 6s?
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
What is the awnser of R plus 2s plus 3R?
It simplifies to: 2s+4R
What is the answer to 3r plus 3r plus 2t?
3r + 3r + 2t = 6r + 2t
How do you solve 7r equals 3r-52?
7r = 3r - 527r (- 3r) = 3r - 52 (- 3r)4r = - 524r / 4 = -52 / 4r = -13
-3r - 8 equals -5r plus 12?
What you want to do is to try and get all the variables on one side by adding/subtracting. Then get the numbers on the other side and solve.
