When multiplying a negative with a positive its always going to be a negative keep that one in mind
so if <span>4x 3=12 that means the answer is -12 because of the negative sign </span>
Answer:
2nd choice
Step-by-step explanation:
If we know one angle of parrellelogram
-9+6 = -3
-5 - 4= -9
so it's
x-3=-9 OR
x=<em>-</em><em /><em>6</em><em />
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.
