I Given mZA= 56.4° and mZB= (2x - 4)", find the measure of each of the following.
18. supplement of ZA
19. complement of ZA
20. supplement of ZB
21. complement of ZB

Factor the polynomial by its greatest common monomial factor.

Consider the function f left parenthesis x right parenthesis equals 4 x squared minus 3 x minus 1f(x)=4x2−3x−1 and complete parts (a) through (c). (a) find f left parenthesis a plus h right parenthesis f(a+h); (b) find startfraction f left parenthesis a plus h right parenthesis minus f left parenthesis a right parenthesis over h endfraction f(a+h)−f(a) h; (c) find the instantaneous rate of change of f when aequals=77.

Can someone answer and tell me how to do this (will mark brainliest)
