Please help me provide an explanation too!

Step-by-step explanation:

The shaded area is the area of the rectangle minus the area of the two circles.

The circles have a diameter of 10.5cm.

The area of each circle is

A=(pi d^2)/4

So the total area of the two circles is

A=(pi d^2)/2

So the shaded area is

A=10.5(21)-(pi (10.5^2)/2

A=220.5-55.125*pi cm^2

A=47.32 cm^2 (rounded to nearest hundredth of a square centimeter)

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
