A12-foot tree casts a 22-foot shadow. find the angle of elevation from the tip of the shadow to the top of the tree. round the answer to the nearest tenth.

Lassify the function as linear or quadratic and identify the quadratic, linear, and constant terms. f(x) = (3x + 2)(−6x − 3) linear function; linear term: −21x; constant term: −6 linear function; linear term: −18x2; constant term: −6 quadratic function; quadratic term: 6x2; linear term: 24x; constant term: −6 quadratic function; quadratic term: −18x2; linear term: −21x; constant term: −6

The product of two negative rational numbers is always zero sometimes zero never zero

Can someone me and plz do the problem
