Please help as soon as possible thank you.

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?

Joey is asked to name a quadrilateral that is also a rhombus and has 2 pairs of parallel sides. should be his answer
