∙ 8y ago9r2-4s2/9r+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
3r + 3r + 2t = 6r + 2t
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.

The chemical formula of strawberry extract can vary depending on the specific compounds present in the extract. However, some common compounds found in strawberry extract include sugars like glucose and fructose, organic acids like citric acid, and various volatile compounds that contribute to the aroma of strawberries.
Cant do much with this one.9r-4s / 9r+6s9r-4s / 3(3r+2s)
5+3R = 5R-19bring all the variables to the left side (in this case it will be R)remember when you bring numbers or variables the sign changes, if the variable or number is positive it shall change to negative and vise versa.3R-5R= -19-5-2R = -24R= -24/-2= 12checking:5+3R = 5R-19so now you substitute R to see if it equation is correct.5+3(12)= 5(12)-195+36=60-1941=41 SO CORRECT!
3r + 3r + 2t = 6r + 2t
7r = 3r - 527r (- 3r) = 3r - 52 (- 3r)4r = - 524r / 4 = -52 / 4r = -13

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.

how do i solve -3r+3r=-6(7+7r)-7(4-7r)
