Modeling and Solving a Problem An isosceles triangle has two sides of equal
length. The third side is 5 less than twice the
length of one of the other sides. If the perimeter of
the triangle is 23 cm, what is the length of the third
side?
Explain how you would define a variable for this
problem.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
