Anyone know how to do this question?

If the three circles are equal, then their diameter is 0.3, because the three diameters of the small circles together span the same space as the diameter of the large circle on the left.

So, the circuit is made by:

The circumference of a circle is given by where r is the radius and d is the diameter. So, the total length is

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
