Step-by-step explanation:
a power supply, a load suited to the power supply, and wiring as a conductor
The first one is 12.5%
the second one is .18
I’m assuming you meant in each shelf there is 14 movies, and there is 4 shelves, so you would multiply 14 x 4 which would be 56 movies
Like terms: in the case of exponents, the same exponents for different numbers
Like 7x and 8x are like terms.
5x and 6x^2 would be unlike terms
Get it??
Good luck~~
