Find the equivalent expression for each of the following ( explain)

(e)=-x-5
(f)=-x+5
(g)-x-3
(h)=-x+3
The explanation for e-f is that when I use the distributive property, the -1 distribute to both the x coefficient and the constant, which is the number inside the parenthesis.
For g-h, its that when you distribute the negative sign, it changes the the signs on the inside, in other words to their opposites.

72 is the mode because it shows up the most number of times
