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
How can you make 2s equal 5?
If 2s = 5 then s = 2.5. So by letting s equal 2.5 (two and one half) you will allow 2s to equal 5.
What does 2s-4 equal?
2s-4 equals 2(s-2). You can find the answer by factoring two out of both numbers.
Two triangles put together?
parallelograms
What is the sum of 2r and 2s?
since you do not know what r and s is all you need to write is... 2r + 2s the sum just simply means add them together.
