1. Jodi has 28 apples. She buys some more. Now Jodi has 43 apples. How many apples did she buy? 143 Use the bar diagram to help you write an equation. Then use the open number line to solve.

What is the multiple zero and multiplicity of f(x) = (x ? 3)(x ? 3)(x + 5)? multiple zero is 3; multiplicity is 2 multiple zero is 5; multiplicity is 1 multiple zero is ? 5; multiplicity is 1 multiple zero is ? 3; multiplicity is 2

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

Solve each quadratic equation by factoring and using the zero product property. 14x - 49 = x^2
