Question

The area, in square feet, of Shawn's garden is found by calculating 15(2x+7). Shawn incorrectly says the area can also be found using the expression 30x+7. What is the correct expression that Shawn should have found? *

Answer 1

The expression for the area is:

`15\cdot(2x+7)=15\cdot2x+15\cdot7=30x+105`

He applied the distributive property but forgot to apply it to the term 7.

The expression for the area after the distribution property is applied is A=30x+105.
