ivan used 5 yards of green for each quilt and 4 yards of blue for each quilt.
Slope of AB=(2-3)/(1+1)=-1/2; AC=(-1-3)/(-3+1)=-4/-2=2; BC=(-1-2)/(-3-1)=-3/-4=3/4.
The product of two sides that are perpendicular is -1. Slopes of AB and AC are perpendicular so angle A is a right angle. ABC is a right-angled triangle.
Question Two is D. $14.80
6x^2 is the answer. thanks for asking it.
