Algebra 2! ! multiply the polynomials (5x^2+8x-6)(8x^2+3x+1) (show work)

30 in the diagram line e and made parallel to each other and line p and q are transversal. use properties of special angles formed by parallel lines and their transversals to find the missing angle measures. m< 3=65 m< 15=120 m< 7= m< 4= m< 6= m< 1= m< 16= m< 18= m< 21= m< 10= m< 11= m< 12=

I’ve been trying all day to figure this puzzle out. i need the work for it aswell. it is a factoring polynomials tarsia. the image is below.

An elevator travels 310 feet in 10 seconds. at that speed, how far can't his elevator travel in 12 seconds?
