A certain manufacturer produces a cars at two factories labeled A and B . 10% of the cars produced at factory A are found to be defective , while 5% of the cars produced at the factory B are defective . If the factory A produced 200,000 cars per year and factory B produced 300,000 cars per year compute the following a. The probability of purchasing a defective car from the manufacturer b. If a car purchasing the manufacturer is defective , what is the probability that it came from factory A

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.

What are “like terms”? why can we only add like terms?
