Jamie is x years old. his friend ana is the same age. write an expression to represent the sum of jamie and ana's ages

2 expressions

x+x

or

2x

A+J

Step-by-step explanation:

Say that J= Jamie

And A=Ana

However their ages are equal so lets have X=Jamie

And X=Ana

Then Y= sum of age

If their ages are the same then you can write it as

x+x=y

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
