Answer:
The bike repair costs $35
Step-by-step explanation:
Common factor of 20= 1,2,4,5,10.......
common factor of 35=1,5,7.............
so here we find that 1 and 5 r the common factors
but the GCF of 20 and 35 is 5
so,
by using GCF the distributive property is : 5(4+7)
The equation of a circle:

(h,k) - the coordinates of the center
r - the radius
The center is (4,0), the length of the radius is 2√3.
3.3333333333..... is the answer
