<h3>

**Answer: 3^5**</h3>

Explanation:

The rule used is

That rule says to go from a negative exponent to a positive exponent, we apply the reciprocal of the fraction.

So,

**Answer:**

Part A:

(2x+7)(5x+9)

(2x*5x)+(2x*9)+(7*5x)+(7*9)

10x^2+18x+35x+63

**10x^2+53x+63**

Part B:

The polynomial has two terms, so is a binomial; also, the polynomial only has one variable, x, and the largest exponent of that variable is 2; therefore is a degree 2 polynomial. In summary, we have a binomial of degree 2.

Part C: Part A demonstrates the closure property for polynomials because after multiplying the polynomials we obtained another polynomial.

**Answer:**

Five pizzas and twenty five hamburgers.

**Step-by-step explanation:**

5 (pizzas) times 5 is 25. That would be the total amount of hamburgers, because 5×5=25

30 (total) - the 25 hamburgers= 5 pizzas
