Answer:
3/5
Step-by-step explanation
Ratio =second term divided inti first term a2/a1
a1=5/12 a2=1/4
1/4: 5/12 is the same as 1/4*12/5 =12/20 = 3/5
5/12*3/5 = 15/60 = 1/4
1/4* 3/5 =3/20
3/20*3/5 =9/100
9/100 *3/5 = 27/500..........
Convert 3 (1/2) into a mixed fraction first and then multiply it by 3:
3(1/2) * 3
(7/2) * 3
21/2
10 (1/2) = answer
6x^2 +30x - 36
6( x^2 +5x -6)
6(x^2 -x+6x-6)
6[ x(x-1) 6(x-1)]
(x-1) (x+6)
