Question

One side of a square is 5n inches long. Another side is n + 16 inches long. Write an equation by setting these equal and solving for n. How long is a side of the square? One point for finding n and one point for finding the length of the side.

Answer 1

5n = n + 16
4n = 16
n = 4

Side of the square is 4

Answer 2

Lord Hades is partially incorrect. n is equal to 4 but the length of the side is 20. (because length = 5n = 5*4)

Answer 3

Agreed. ^^

Answer 4

n=4 and one side of the square= 20 in. Don't forget your units!

Answer 5

It doesn't give the units in the question lol.

Answer 6

@Lord Hades, yeah it does--the question directly states, "5n inches long," etc.

Answer 7

Solve the following simultaneous equations for s and n:
{ s = 5 n, s = n + 16 }
s = 20, n = 4
