What is the value of 7(23)? Use place value and the distributive property.
kkurt [141]

Answer:

7(23) = 161

Step-by-step explanation:

Using the Distributive Property, you put the 7 into the number 23.

We have to think of place value as well. Since there is a parenthesis you have to add the 20 and 3 first.

7(23) = ?

This you are going to use the Distributive Property for.
