Answer:
(160+8)*4
Step-by-step explanation:
You're probably not bad at math but practicing often makes you more confident.
This question is asking you to find an expression that represents a sum of two terms which is multiplied by 4. There's really only one alternative that has a multiplication by 4 but let's anyways start by thinking of what is defined as a sum.
- A sum is the result of adding two (or more) terms.
- Similarly the result of subtracting two terms is called a difference.
- The result of multiplying two (or more) terms is called a product.
- The result of dividing two terms is called a quotient.
The sum of 160 and 8 is therefor an addition 160 + 8.
To denote that we want to multiply the whole sum by we put the sum in parenthesis before we multiply. It will then look like (160+8)*4.
This expression well matches the third option.
