Find all possible ROCs for the following z-transforms and determine the associated inverse ztransform for each case. (a) z 2 − 2z z 2 + 4z + 3 (b) 1 (1 − 1 2 z−1)(1 − 1 3 z−1)

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

im guessing (23,14). hope this : )
