Answer:
The answer is 544. The distributive property is a property that basically says that any number outside the parenthesis can be multiplied and distributed between all other numbers in the parentheses.
Explanation:
17(11+21) = [This is the given equation]
17*11 + 17*21 [I used the distributive property]
187+357 [I used a calculator for the sake of time, but I suggest when double digit multiplying, do it by paper.]
= 544 [The answer is 544.]
The distributive property is a property that basically says that any number outside the parenthesis can be multiplied and distributed between all other numbers in the parentheses. An example is w(x+y+z). w(x+y+z) can also be simplified to (wx+wy+wz) because w is being distributed between all variables in the parenthesis. You can also get rid of parenthesis after simplifying.
The distributive property is also used when doing 'F.O.I.L'.
