Question

What do I do to solve this?

"A plot of land is in the shape of a triangle. If one side is x meters, a second side is (2x-3) meters, and a third side is (3x-5) meters, express the perimeter of the lot as a simplified expression in x."

Answer 1

First let's write it down,

x + (2x - 3) + (3x - 5)

Then remove the parentheses

x + 2x - 3 + 3x - 5

first combine the x + 2x = 3x to obtain: 3x - 3 + 3x - 5

then combine the 3x + 3x = 6x to obtain:

6x - 3 - 5

rewrite 6x - 3 - 5 as 6x + (-3) + (-5)

And the answer would be 6x + (-8) =

6x - 8
