The expression for the area of the shaded region is s^2 - pir^2
<h3>Area of composite figure</h3>
The formula for calculating the area of the shaded part in the given equation is expressed as:
Area area of square. - area of circle
Since
Area of square = s^2
Area of circle = pir^2
substitute
Area of shaded part = s^2 - pir^2
Hence the expression for the area of the shaded region is s^2 - pir^2

Substitution would be a great approach to solving this system, because the first equation defines y as x - 10 and you can thus substitute x - 10 for y in the second equation:
2x + (x - 10) = 4
Then 3x - 10 = 4, and 3x = 14. Solving for x: x = 14/3.
Since y = x-10, subst. 14/3 for x to find y: y = 14/3 - 30/3 = -16/3
The solution is (14/3, -16/3).
