Question

Find the total mass of the triangle region in the figure below, which has density that equals 2+x. The triangle goes from -2 13 years ago

Answer 1

What figure?

(Diagram.)

Answer 2

From some googling, I get

\[\large \textrm{density} = \frac{\textrm{mass}}{\textrm{area}} \]
\[\large{ d = {m \over A} \\ \ \\
m = Ad }\]

Plug in the values for area of the triangle and density.

Answer 3

Do i need to use some form of integral?

Answer 4

I have no clue; never done this before.
