Answer:
first off, your answer isn't wrong. all you need to do is multiply through by 3. Then you'll get the answer in the format you want.
Hope this helps
I'll do the 2d problem to show you how it's done; always remember your order of operations - PEMDAS (Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction).
6h - (9 - 3h) = 6 - 3(h + 2) Distribute what's in front of the parenthesis to the inside
6h - 9 + 3h = 6 - 3h - 6 combine like-terms on both sides
9h - 9 = - 3h Isolate the variable onto one side
12h = 9 Divide by 12 to get the variable alone
h = 9/12
8) factor 6+17g+10g^2
10g^2+17g+6
(5g+6)(2g+1)
C is the answer.
9) which one is a perfect square?
4x^2-14x+49 doesn't factor
4x^2-28x+49=(2x-7)(2x-7)
x^2-x+1 doesn't factor
x^2-2x+2 doesn't factor
B is the answer.
11) factor y^2-2y-48
(y+6)(y-8)
D is the answer
12) for the last one you can multiply the answers out of factor.
Sorry this took forever. It's hard to use the website cuz I'm used to the app.
Best wishes!
