<h3>Area of shaded region = 6.88 square inches</h3>
Step-by-step explanation:
Area of shaded region
When we subtract the area of the circle from the area of square, we get the area of the 4 corners. When we divide that by 2, we get the area of 2 corners(shaded).

<h3>Square: </h3>
Area of square = side *side
= 8 * 8
= 64 square inches
<h3>Circle:</h3>
diameter of the circle = side of the square
d = 8 in
r = 8/2 = 4 in
Area of circle = πr²
= 3.14 * 4 * 4
= 50.24 square inches

Answer:
The number of nickels, x is 4
The number of dimes, y is 16.
Explanation:
Given that Melanie has $1.80 worth of nickels and dimes, and she has 12 more nickels than dime.
Let x represent the number of nickels and y represent the number of dimes.
Then we have:
0.05x + 0.1y = 1.80 ...................................................(1)
x + 12 = y.....................................................................(2)
Solving these equations using graph as follow:
Note that the solution are the points where the lines intersect.
Here, x = 4 and y = 16
