Answer:
1/3
Step-by-step explanation:
To simplify, you have to divide both of the numbers by the largest number that divides into both of them equally
In this instance, it's 13
13/13 = 1
39/13 = 3
Thus giving us 1/3
x=4/3 , x=-5/2
6x^2 +7x=20
6x^2+7x-20=0
(3x−4)(2x+5)
3x-4=0 , 2x+5=0
3x=4 , 2x=-5
942 square cm
