To prepare premium rates (the amounts customers pay) for an insurance plan, an insurance company conducts an extensive risk study to determine the probability that a member of a certain group may require a pay-off. Based on these probabilities, the expected amount of payoff is charged to the consumer as part of the premium. Explain why car insurance companies charge a higher premium for teenage drivers with a clean driving record than for adult drivers with a clean driving record.

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
