No, it won't change the outcome.
-8k - 8(-8k + 6) = -8k + 64k - 48 = 56k - 48
Option C
The distance of a spin of one full rotation is 31.4 feet
<em><u>Solution:</u></em>
Given that,
A circular merry-go-round has a radius of 5 feet
Radius = 5 feet
We have to find the distance of spin for one full rotation
Distance covered in 1 full of rotation is equal to circumference of circle
<em><u>The circumference of circle is given as:</u></em>

Where "r" is the radius

Thus the distance of a spin of one full rotation is 31.4 feet
18 because it has equal so that means that you divide
3 to the third power = 9
2 Open Bracket 64 - (3 x 7) close bracket = 86
9 + 86 = 95
