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
It simplifies to: 2s+4R
-6r 2s 5t 2
(2S,3S)-2,3-Pentanediol and (2R,3R)-2,3-Pentanediol
3r + 3r + 2t = 6r + 2t
how do i solve -3r+3r=-6(7+7r)-7(4-7r)
7r = 3r - 527r (- 3r) = 3r - 52 (- 3r)4r = - 524r / 4 = -52 / 4r = -13
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.
3R is Recycle,Reduce and Reuse
(3r - 2)(3r - 2) or (3r - 2) squared.
3r-r equals 12 = -9
pessimistic and hopeless (r!++3r
Sodium chloride is NaCl.Sodium hyaluronate has a very long and complicate name:Sodium (2S,3S,4R,5R,6R)-3- [(2S,3R,4R,5S,6R)-3-acetamido-4-[(2R,3R,4S,5S,6S)-6-carboxy-3,4,5-trihydroxyoxan-2-yl]oxy-5-hydroxy-6-(hydroxymethyl)oxan-2-yl]oxy-6-[(2R,3R,4R,5S,6R)-3-acetamido-2,5-dihydroxy-6-(hydroxymethyl)oxan-4-yl]oxy-4,5-dihydroxyoxane-2-carboxylic acid.
Cant do much with this one.9r-4s / 9r+6s9r-4s / 3(3r+2s)
Exactly as in the question: 3r-1
(3r - 8)(3r - 8)
1/99 − 1/100 = 1/9900
3r + 12 = 3*(r+4)
If that's 3r + 12, that factors to 3(r + 4)
(r + 1)(3r - 5)
3r+10=5r-46 --> add 46 to both sides 3r+10+46=5r-46+46 3r+56=5r --> subtract 3r from both sides 3r+56-3r=5r-3r 56=2r --> divide both sides by 2 56/2=2r/2 28=r
r - 10 + 100 - 3r = -2r + 90
(3r + 2)(r - 5)
