Rectangle ABC, B, C, D is graphed in the coordinate plane. The following are the vertices of the rectangle: A(5, 5), C(7,-1), and D(5,-1)D(5,−1)D. Given these coordinates, what is the length of side BC of this rectangle?

Talia grouped the terms and factored out the gcf of the groups of the polynomial 15x2 – 3x – 20x + 4. her work is shown below. (15x2 – 3x) + (–20x + 4) 3x(5x – 1) + 4(–5x + 1) talia noticed that she does not have a common factor. what should she do?
