Help ! Please ! If a/2 - b/3=1 , what is 2a+3v in terms of b?

ArbitrLikvidat [17]

A/2-b/3=1 solve for a, add b/3 to both sides

a/2=1+b/3 which is equal to

a/2=(3+b)/3 multiply both sides by 2

a=(6+2b)/3 now you can substitute this into 2a+3b giving you:

2(6+2b)/3 + 3b which is equal to

(12+4b+9b)/3

(13b+12)/3

Answer:

$f(x)=\dfrac{x+2}{2(x-2)}$

Step-by-step explanation:

Remember when you divide fractions, you need to get the reciprocal of the divisor and multiply. So your first simplification would be:

$\dfrac{x^2+4x+4}{x^2-6x+8}\div\dfrac{6x+12}{3x-12}\\\\=\dfrac{x^2+4x+4}{x^2-6x+8}\times\dfrac{3x-12}{6x+12}\\\\=\dfrac{(x^2+4x+4)(3x-12)}{(x^2-6x+8)(6x+12)}$
