Question

3 time the sum of twice a number r and 83(2r-8)3/2r + 83(2r+8)

Answer 1

We have to write the expression for "3 times the sum of twice a number and 8​".

Twice a number can be written as 2r, where x is the number.

The sum of twice a number and 8 can be written as 2r+8.

Then, three times this sum is 3(2r+8).

Answer: we can write the expression in mathematical terms as 3(2r+8) [third option]
