A park has a pond shaped like a quadrilateral with side lengths 15 feet and no right angles. what geometric shape best describes the shape of the pond. Sketch the pond

How do i simply this expression (quadratic formula basis) on a ti-84 or normal calculator?

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 5x^2 + 10x

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.
