In δabc, m∠abc = 40°, bl is the angle bisector of ∠b with point l∈ ac . point m ∈ ab so that lm ⊥ ab and n ∈ bc so that ln ⊥ bc find the angle measures in δabc if m∠cln = 3m∠alm and prove that cn = 1 /2 cl.

Tim's phone service charges $23.06 plus an additional $0.22 for each text message sent per month. if tim's phone bill was $28.56, which equation could be used to find how many text messages, x, tim sent last month?

Use the distributive law to multiply. 3(4x + 5y + 6)

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
