Can someone please tell me how to get from that to that? Is it factorization or something? I’m really dumb

They multiplied the 4's to get 16.

For the X part, 1 of the X's got cancelled out.

So like this:

X divided by X² would leave you with an extra X.

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
