What is the sum of the rational expressions below? 2x/ x+2 + x/ x-3

3x^2-4x/x^2-x-6

Step-by-step explanation:

How to find denominator:

Since the expressions do not share the same denominator, we must find the common denominator. To do that, you must multiply (x+2)(x-3). That gives us x^2-x-6. So, x^2-x-6 is the denominatar.

How to find numerator:

Because we multiplied x+2 by x-3 we must multiply the numerator of that expression by x-3. Which gives us 2x^2-6. To add on, Because we multiplied x-3 by x+2 we must multiply the numerator of that expression by x+2 as well. Which gives us x^2+2x. We add 2x^2-6x and x^2+2x to get the simplified numerator, 3x^2-4x.

I Hope this helped. ~_~

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
