LOGICAL REASONING Decide whether the statement is true or false If false, rewrite the right-hand side of the equation so the statement is true. $$ 3(2+7) \stackrel{?}{=} 3(2)+7 $$
DISTRIBUTIVE PROPERTY Use the distributive property to rewrite the expression without parentheses. $$ 2(3 x-1) $$
Use the distributive property and mental math to simplify the expression. $$ 3 x^{2}+4 x+8-7 x^{2} $$
Write the verbal sentence as an equation or an inequality. Nine more than three fourths of \(y\) is less than six times \(w\)n.
LOGICAL REASONING Decide whether the statement is true or false If false, rewrite the right-hand side of the equation so the statement is true. $$ \frac{2}{9}\left(\frac{1}{3}-\frac{4}{9}\right) \stackrel{?}{=} \frac{2}{9}\left(\frac{1}{3}\right)-\frac{2}{9}\left(\frac{4}{9}\right) $$
