Answer:

$(5-x)/(3x+4)(2x - 3)$

Step-by-step explanation:

Given that:

$(4x +5/6x^2 -x-12) - (5x/6x^2-x-12)$

As denominator is same so by subtracting the numerators we get:

$4x+5 -5x/6x^2-x-12\\5-x/6x^2-x-12$

By making factors of the denominator we get:

$5-x/6x^2 +8x -9x -12\\5-x/2x(3x +4) -3(3x+4)\\5-x/(3x+4)(2x - 3)$

Hence it is the simplified form of given question..

I hope it will help you!

Can someone please help me on this question? Use the following diagram to find the fraction representing each collection of dots

ale4655 [162]

Answer:

a. 4/7

e. 3/4

Step-by-step explanation:

For each part of the question, count the dots that meet the first requirement, and count the dots that meet the "fraction of ..." requirement. The desired fraction is the ratio of these numbers. In the answers above, we have reduced the fractions to lowest terms, but the question does not seem to require that.

a. The desired fraction is ...

(dots in the triangle)/(all dots) = 16/28 = 4/7

e. (dots in the rectangle not in the circle)/(dots in the rectangle) = 9/12 = 3/4
