Question

Points A, B, C, and D are collinear and positioned in that order. Find the length indicated. AD=3x+5, CD= 3, BC = x, and AB = x +5. Find BC​

Answer 1

Explanation:

x=-11we know thatPoints A,B,C,and D are collinear and positioned in that ordersoAD=AB+BC+CD -----> by addition segment postulatewe haveAB=2x+30AD=x=32substitute the given values and solve for xx+32 = (2x+43)Group terms that contain the same variable2x-x=32-43x=-11
