Solve the equation.y2 + 6y = 40

Find every value for the variable that makes the expression undefined.

Solve. = x – 1

Use the square root property to solve the given equation.(p – 2)2 = 7

Simplify. Assume that variables represent nonnegative numbers.

Determine whether the graphs of the equations are parallel lines, perpendicular lines, or neither. 3x – 6y = 1318x + 9y = 13

Factor the trinomial.x2 + 3x – 40

Factor the polynomial by grouping.ac + 12a – 9c – 108

Determine the slope and the y-intercept.y = 7x + 5

Any law can be repealed by Congress. But the law of gravity is also a law, so I guess the law      of gravity can also be repealed by Congress.
