sqrt(160)
Factor.
s2 – 5s – 14
What is (s + 2)(s - 7)?
What is the midpoint between the points (–1, 2) and (3, –6)?
What is (1, -2)?
What is the sum of the distance between the points A(–1, 2) and B(3, –6) & C(4,4) and D(-5,9)? (Round answer to nearest tenth)
bar(AB) = sqrt(80) = 8.9
bar(CD) = sqrt(106) = 10.3
8.9 + 10.3 = 19.2
