Sylvie bakes 4 trays of muffins. Each tray contains 8 muffins. She gives away 12 muffins to friends. Let m represent the number of muffins Sylvie has left. Which equation could be used to find the value of m? 4 + 8 + 12 = m 4 × 8 + 12 = m 4+8−12=m 4×8−12=m

What number should be added to both sides of the equation to complete this square? x^2-10x=7
