Choice C , Company C and Company D. hope I helped.
Since the standard deviation is the square root of variance. The only times where the standard deviation is greater than the variance is when the variance is between the values 0 and 1 exclusively. For example, the square root of 0.25 is 0.5.
(3x+1)+(2x+4)=90
3x+1+2x+4=90
5x+5=90
5x=85
x=17
The answer is D. I graphed it on this website called desmos. The solution is where the lines intersect.
Answer:
1(A)X=3/12

=4
1(D)X=8+4
=12
