# Terms of a Variable

For some reason, as if fate won't allow it, I have never fully understood what "in terms of a certain value" meant. For example, in the following problem: One side of a triangle is x inches longer than another side. The ray bisecting the angle formed by these sides divides the opposite side into 3 and 5 inch segments. Find the perimeter IN TERMS OF x. I usually put x on one side of the equation and solve for the other side. However, what does this actually mean?

In an informal manner, that value can be present somewhere in the required expression.

I don't think that it must be present. I think it's more that it can be present.

What would you definition be?

"Express $$A$$ in terms of $$B$$" means write an expression for $$A$$ which only uses constants and/or the variable $$B$$. Most of the time, you are likely to use B, but that is not always guaranteed (esp if they are trying to mislead you).

Ok, I understood. Thanks for the help!
