x/9 +3 = 8 - x/3 Solve?????? First, get rid of the fractions to make the equation easier to solve for x. Let's multiply every term by 9: 9 [x/9 + 3 = 8 - x/3] x + 27 = 72 - 3x 4x = 45 x = 45/4 Substitute 45/4 for x in the original equation to check. It always helps to chec...

algebra
-5k + 15 _________ k2 - 9 Does this facot to -5(K+3) _______ k^2 -9 Is this right? Nope. You have to factor the denominator to (k+3)(k-3) The numerator you factored should have been -5(k-3), you missed a sign.

algebra
7 -y _____ Y - 7 Does this factor to 1???? Assuming that the two Ys (y and Y) indicate the same unknown, it would be -1. (7 - Y)/(Y - 7) = -1(Y - 7)/(Y - 7) The (Y - 7) terms cancel each other out, leaving -1. I hope this helps. Thanks for asking.

algebra
8a + 8b _______ 12c + 12d factor to a + b _______ c + d Is this right? No, what happend to the 8/12 ? would it be 2 (4a + 4b) _____________ 6 (2c + 2d) Is this right??? No. what about ..lets see, 8/12 reduces to 2/3, so 2(a+b)/3(c+d)

Find the factors ab+ 2a +3b +6 First group the terms to get (ab+2a) + (3b+6) Now you can find a factor for each term a(b+2) + 3(b+2) Factor out the (b+2) in each term (b+2)(a+3)

algebra
complete factorization y^4-25y^2+144 (^) denotes following number is Power y^4 - 25y^2 + 144 You might try replacing y^2 with x. Therefore your statement becomes: x^2 - 25x + 144 ...which is easier to factor.
