The perimeter of a square is a^2. In this case a= (4x-2y) so a^2=(4x-2y)^2 , a^2={16(x)^2-16xy+4(y)^2}
A = π(r²) --- r is radius
C = πd --- d is diameter
First, the circumference must be found. If the circumference is 15.7, plug it in.
15.7 = πd
We know what pi is.
15.7 = 3.14 (d)
Now, simply divide 3.14 by 15.7 to find the diameter (d). You get 5. Since the radius is half of the diameter, the radius is 2.5. Plug this into the area formula, and plug pi in, too.
A = 3.14(2.5²)
2.5 to the second power is 6.25.
A = 3.14(6.25)
Tada! Multiply, and you're left with 19.625!

If i plug it into my calculator i get 9914 as my answer,
Explanation:
but if that’s not the right answer lmk and i can solve it a different way!
2/5 = 0.4
let x = amount of applications received
180 = 0.4x.
Divide each side by 0.4
450 = x
The school received 450 applications
