Find the limit (if it exists). (if an answer does not exist, enter dne.) lim x→(−1/2)+ 6x2 + x − 1 4x2 − 4x − 3

Explain step-by-step how to simplify -5(2x – 3y + 6z – 10).

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown

Find the value of x. give reasons to justify your solutions! l, m ∈ kn
