A triangle has a base of x and a height of x+4. If the area is equal to 30, what is the value of x

Which is the completely factored from of xy^3-x^3y

If two lines form congruent alternate interior angles with a transversal, then the lines

The function below is written in vertex form or intercept form. rewrite them in standard form and show your work. y = 5(x+3)^2-4
