Solve the problem.A recipe calls for 4 ounces of unsweetened chocolate for 6 brownies. How much of unsweetened chocolate is needed to make 16 brownies?

Graph the set of real numbers on a number line.{x|x ≤ 2}

Factor the trinomial, or state that the trinomial is prime. Check your factorization using FOIL multiplication.8×2 + 18x + 9

Solve and check the equation.8x – (2x – 1) = 2 1.

Graph the set of real numbers on a number line.{x|x > 1}

Use FOIL to find the product.(4x – 6)(x – 11)

Use properties of exponents to simplify the expression. First, express the answer in exponential form. Then, evaluate the expression.23 ∙ 26

Solve the proportion. = 1.

Solve the inequality and graph the solution set.-9x ≥ 18

Factor the trinomial, or state that the trinomial is prime. Check your factorization using FOIL multiplication.6×2 + 17x + 12
