“m∠aoc = 7x – 2, m∠doc = 2x + 8, m∠eod = 27 how do you do this problem?

Which of the following represents a number squared is equal to twenty more than nine times that number ? a) x squared = 9x + 20 b) x squared = 20x + 9 c) x squared > 9 + 20x d) x squared = 9 + x + 20

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10
