Answer:

Explanation:
Hello.
Multiply 4 times 7 and -2:
4*7=28
4*(-2)=8
Write the expression together:
28-8
Are 28 and -8 like terms? Sure, because they are both constants; they are from the same family (family of constants).
Therefore, this expression can be simplified:
20
There's another way to consider it.
And that is:
- Subtracting 7-2 and multiplying the result by 4.
- The result will be 20 anyway :)
And we're done!
I hope it helps & have an outstanding day!
