140
143
161
164

Answer 1

Distribute 7 to both of the terms in parentheses:


`7 * 20 = 140`

`7 * 3 = 21`

`140 + 21 = 161`

The answer is 161.

Answer 2

Option C.

Explanation:

The given expression is

`7(23)`

Write 23 as he sum of its place values.

`7(23)=7(20+3)`

Using distributive property we get

`7(23)=7(20)+7(3)`

`7(23)=140+21`

`7(23)=161`

The value of 7(23) is equal to 161. Therefore, the correct option is C.
