Exercise 12 Page 111

Rewrite each term as a product of the coefficient of the variable term and some other factor.

3.5(12+h)

Practice makes perfect
We want to factor out the coefficient of the variable term — 3.5. Let's rewrite each term as a product of 3.5 and some other factor. To do so, note that 42 is 12 times 3.5. 1{42 &= {\color{#FD9000}{3.5}} \cdot 12 \\[0.5em] 3.5h &= {\color{#FD9000}{3.5}} \cdot h } Now we can use the Distributive Property to factor the expression. Let's go!
42 + 3.5h
