How would I solve this

[From: ] [author: ] [Date: 12-04-28] [Hit: ]
or you could swap the words width and length in the above.Plug in z = 4 into these expressions.......
The amount of paint needed to cover a wall is proportional to its area. The wall is rectangular and has an area of 4z^2+2z square meters. Factor this polynomial to find possible expressions for the length and width of the wall. (Assume the factors are polynomials.) If z=4 what would the length and width be?

-
4z² + 2z = 2z(2z + 1)

So

the width could be 2z meters and the length 2z + 1 meters
the width could be z meters and the length 2(2z + 1) meters
the width could be 2 meters and the length z(2z + 1) meters

or you could swap the words "width" and "length" in the above.

Plug in z = 4 into these expressions.
