Yes
factor out the 2z^2 in each term
(2z^2)(z^2-5z+4)
factor some more
z^2-5z+4
find what 2 numbers multiply to get 4 and add to get -5
the numbers are -1 and -4
(z-1)(z-4)
the factored form is
(2z^2)(z-1)(z-4)
40 Why? 80%x X=50 or 80/100x X=50
The graph is not proportional because it doesn’t go though the origin aka (0,0)
5 1/4 as a decimal is 5.25
this is because 1/4 is equal to 25/100
Answer:
