Answer 1

19 x (42 + 58)

Explanation:

The common term is 19

Answer 2

Answer : The expression she use can be,
`19* (42+58)`

Step-by-step explanation :

Distributive property Law : It says that multiplying a number by the group of numbers added together is the same as doing each multiplication separately.

For example:

3 × (2 + 4) = 3×2 + 3×4

As we are given the expression:

`19* 42+19* 58`

`\Rightarrow 19* (42+58)`

Thus, the expression she use can be,
`19* (42+58)`
