Simplify the expression by combining like terms. Write the terms from the highest to the
lowest power of the variable.
7b^2- b + 3b + 6 - 3b^2+ 5 + 2b^2+ 7b

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

Use the discriminant to describe the roots of each equation. then select the best description. 2m2 + 3 = m double root real and rational roots real and irrational roots non-real roots

The center of the circumscribed circle lies on line segment and the longest side of the triangle is equal to the of the circle.
