You have to combine equal terms. -5r-9s+9r+3s-6 = -5r+9r-9s+3s-6 = 4r-6s-6
-9r plus 10r can be written as ( -9r + 10r) and the answer is r.
3+10-r+6r = -3+9r+0 13+5r = -3+9r 16 = 4r r = 4
Combine the ' 9r ' and the ' -5r ' . Replace them with ' 4r '.
It is 5n + 9r.
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
83-9r = 74
3(g + 6b + 3r)
The LCM is r^3 + 9r^2 - 25r - 225.
-9r = 20 + rsubtract r from both sides-10r = 20divide both sides by -10r = -2
9r-- think of the 'r' as '1r' and add like you normally would.
(3r - 2)(3r - 2) or (3r - 2) squared.
9r = 3r + 6 subtract 3r from both sides 6r = 6 divide both sides by 6 r=1 ■
(9r - 8)(9r + 8)
No. A polynomial is an expression of more than two algebraic terms, and usually contains different powers of the same variable.
9r = 3r+6 Subtract 3r from both sides: 6r = 6 Divide both sides by 6 to find the value of r: r = 1
The engine size of a 2002 Kawasaki ZX900FI Ninja ZX-9R motorcycle is 899cc (cubic centimeters).
If we assume that "r" is unknown: -9r+8 or 8-9r It cannot be simplified further.
The answer is -r
3r - 9r = 18 wright equaton -6r = 18 combine like terms r = -3 solve
