On questions such as the area is 3 times the square root of 2 + 5, how would you solve that algebraically?

? My teacher has taught us two different methods to do so, such as foiling and square rooting it in the calculator, then square rooting it again, and square rooting each of the choices until it matches up. Please help!

Area = 3v2+5 is not a question, it's a statement and doesn't require algebra to solve. In this case, Area ˜ 3*1.4+5 = 9.2 units2. What is the question asking you to solve for?

Your square root should read sqrt (x^2) = sprt 9 + sqrt (2=5) x = 3 X rad (7)

Hi, Bill.

I read it as 3 rad 2 plus 5 (plain).  A rad 2 term is not like a plain 5 term.  Again, the original question was not clear.
