Complete the distribution. (Do NOT use spaces or parenthesis in your answer, it will count it wrong.)
–3 (2x – 3y = –15)

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

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

School has 204 sixth grade students. if the sixth grade is 30% of the total school, how many students are in the middle school?
