Question

3-98. With your team, examine the equations you wrote for parts (b), (c), (g), and (h) of problem 3-97. This pattern is the simplest form of what mathematicians call the Distributive Property. Multiply the following expressions without an area model to write them as sums instead of products. Be ready to share your process with the class. a. 2r(61 +5) b. 6(4.1 -1) C. x2 (40 - 2y) d. 7 (10x + 11g) e. -5x(31 - 8)

Answer 1

We need to multiply using Distributive Property

`\begin{gathered} 7y\cdot(10x+11y) \\ \\ =7y\cdot10x+7y\cdot11y \\ \\ =70xy+77y^2 \end{gathered}`
