When you subtract a negative number it becomes an addition:

20 3/4 - -15 3/8 becomes:

20 3/4 + 15 3/8

Rewrite the fractions to have a common denominator:

3/4 = 6/8

Now you have 20 6/8 + 15 3/8

6/8 + 3/8 = 9/8 = 1 1/8

Now you have 20 + 15 + 1 1/8 = 36 1/8

The answer is 36 1/8

Answer:

The box to the left will have the equation p(x) = 5x² and the box to the right will have the equation n(x) = $\frac{1}{5} x^{2}$

Step-by-step explanation:

The coefficient of the x² decides how wide or narrow a quadratic graph is. If the coefficient is a fraction of 1, the smaller the fraction the wider the graph gets. If the coefficient is a number bigger than 1, the bigger the number, the narrower the graph gets.
