How to find this anwser you would have to take the 8 and distribute it to the m and 3 in side the (), than you can solve it easily. 8(m+3)-20+m = 8m+24-20+m=8m+4+m=9m+4 and there is your anwser!

False, I believe. Not so sure if you can make a triangle out of three sides that are not the same size

Answer:

x = +-sqrt(3) and they are the actual solutions

Step-by-step explanation:

x^2/ (2x-6) = 9/(6x-18)

get a common denominator of 6x-18

x^2/ (2x-6) * 3/3 = 9/(6x-18)

3x^2/ (6x-18) = 9/(6x-18)

since the denominators are the same, the numerators must be the same

3x^2 = 9

divide by 3 on each side

x^2 = 3

take the square root of each side

sqrt(x^2) = +-sqrt(3)

x = +-sqrt(3)
