Solve step by step:
( - 2x + 6)^1/5 = ( - 8 + 10x)^1/5
step 1: Cross Multiply
(( -2)(x) + 6)^1/5 = ( - 8 + 10x)^1/5
(( - 2)(x) + 6)^1 * (5) = ( - 8 + 10x)^1 * (5)
- 10x + 30 = 50x - 40
Step 2: Subtract 50x from both sides
- 10x + 30 - 50x = 50x - 40 - 50x
- 60x + 30 = - 40
Step 3 Subtract 30 from both sides
- 60x + 30 - 30 = - 40 - 30
- 60x = - 70
Step 4 Divide both sides by - 60
- 60x/ - 60 = - 70/ - 60

Answer:
B. (x+2) is a factor
Step-by-step explanation:
3x^2 -x-14
3x^2+6x-7x-14
3x(x+2)-7(x+2)
(3x-7)(x+2)
so, x+2 is a factor of 3x^2-x-14
Geo is
an=a1r^(n-1)
2nd term is 12
4th term is 4/3
a2=a1r^(2-1)=12
a2=a1r=12
a4=a1r^(4-1)=4/3
a4=a1r^3=4/3
we have
a1r=12 and a1r^3=4/3
(a1r^3)/(a1r)=r^2=(4/3)/12=1/9
1/9=r^2
sqrt oth sides
1/3=r
the common ratio is 1/3
