The sum of the measures of angle M and angle R is 90°. • The measure of angle M is (4x+15). • The measure of angle R is 35°. What is the value of x?

Which value of m will create a system of parallel lines with no solution? y = mx - 6 8x - 4y = 12

Astudent was asked to find the square of 7x+3. the student quickly wrote (7x+3)^3= 49x^2+9. identify the student's error and provide the correct answer.

3questions show how you solved the problem 1. subtract & simplify (–y2 – 4y – 8) – (–4y2 – 6y + 3) 2.multiply and simplify 2x2y3z2 · 4xy4x2 3.multiply and simplify (x – 4) (x2 – 5x – 6)
