Subtract 17 from both sides
9= -d+17
9 - 17 = -d + 17 - 17
-8 = -d
Then divide.
-8/1 = -d-1
Cancel terms that are in both numerator and denominator

10•4=40. 40 is the perimeter of the square. To find the perimeter of the semicircle use the circle perimeter (circumference) formula and divide that answer by two. This would be pi•10. You get 31.4. Then divide by 2 so it’s 15.7. Finally add 15.7 and 40. Hope this helps... sorry it’s such a long answer
8.68x when x=the amount of hours you have worked
