A coat costs 3 times as much as a pair of pants. Together they cost $180. How much does each Cost? B) find the area of a square with sides (× + 10).

Answer 1

Let's say that the pair of pants costs an x amount. Based on the information given, the coat would be 3x.

We know that the Toal is $180.

x + 3x = 180

4x=180

x=45

The area of a square is equal to the length of side A multiplied by the length of side B. Since both sides are the same length, it's squared.

We know that one side is equal to (x+10).

So, the area is (x+10)^2

If we expand that we get x^2 + 20x +100
