19. Geometry The formula for the perimeter of a rectangle is 2l 1 2w, where l is the
length and w is the width. How can you use the Distributive Property to write an
equivalent expression for 2l 1 2w? Explain.
20. Writing to Explain Eliot uses the Distributive Property to write an equivalent
expression for 7(3x 1 4). He writes 21x 1 4. Emma notices that Eliot made a
mistake. How could Emma explain to Eliot where he went wrong? What is the
correct equivalent expression?
Use the Distributive Property to write an equivalent expression by filling
in the missing numbers.
Find the missing number(s) so that the expressions are equivalent.
Use the Distributive Property
