The area is 81*pi-162. Look at the triangle formed by the chord and the two radii connected to the endpoints of the chord. Since 18^2+18^2=(18*\sqrt2)^2, this is an isosceles right triangle by Pythagorean theorem. The area of the quarter circle containing the region we look for is pi*18^2/4=81*pi. The area of the right triangle is 18*18/2=162. The difference between these two areas, or 81*pi-162, is the area of the smaller region.
X = -3
Solution:
Distribute
6(x)+(6)(-1)+-x=-21
Combine
(6x+-x) + (-6) = -21
5x + -6 = -21
5x - 6 = -21
Add 6 to both sides
5x -6 + 6 = -21 +6
5x = -15
Divide both sides by 5
5x/5 = -15/5
x = -3
