# How do you translate into a mathematical expression: Twice the sum of eight more than a number?

Sep 27, 2016

#### Answer:

$2 \left(x + 8\right)$

#### Explanation:

The word "SUM" means ADD and should always be used with the word "AND" to indicate which numbers are being added,.

In this case, I suspect the expression could be written as.
"Twice the sum of 8 and a number"

The sum of 8 and a number is written as $8 + x$

"Twice" means "double" or multiply by 2.

$2 \left(x + 8\right)$
