Question

Which equation could represent "the perimeter of a square as a function of a side"? p(x) = (1/4)(x) p(x) = 4x p(x) = 4 + x

Answer 1

Perimeter is the distance around a two-dimensional shape (it is the sum of the length of the sides), in our case the shape is square. A square has 4 equal sides. So, the perimeter is: p(x)=x+x+x+x= 4x

The equation that represent "the perimeter of a square as a function of a side" is:

p(x) = 4x
