Solve the problem.A recipe calls for 6 ounces of unsweetened chocolate for 8 brownies. How much of unsweetened chocolate is needed to make 16 brownies?

Use properties of exponents to simplify the expression. First, express the answer in exponential form. Then, evaluate the expression.33 ∙ 32

Solve the problem.The formula P = 0.69×2 – 0.046x + 3 models the approximate population P, in thousands, for a species of fish in a local pond, x years after 1997. During what year will the population reach 36.488 thousand fish?

Use FOIL to find the product.(4x + 4)(x + 1)

Factor the trinomial, or state that the trinomial is prime. Check your factorization using FOIL multiplication.x2 – 4x – 12
