Solution:
we are given that
Diego is building a kitchen table and a coffee table. The legs of a kitchen table must be twice the height of a coffee table and there are 4 legs on each table.
He writes the expression [tex]4(2x) + 4(x)[/tex] to model his building plans.
Here we can see one thing---x and 2x
and the question says
The legs of a kitchen table must be twice the height of a coffee table
It mean coffee table leg length[tex]=x[/tex]
Kitechen table leg length[tex]=2x.[/tex]
But in the expression each term has a multiple of 4. It mean it include length of all the four legs.
Hence we can say
4(x) represents the total length of all four coffee table legs.
