What is the formula for the perimeter of a triangle?

Back

The perimeter P of a triangle with sides a, b, and c is given by P = a + b + c.

Front

If the perimeter of a triangle is 24 inches, what equation can represent the side lengths in terms of x and y?

Back

x = \frac{23 - 5y}{3}

Front

What does the y-intercept of a linear equation represent?

Back

The y-intercept represents the value of y when x is 0, indicating the starting point of the relationship.
