Question

How do you write the phrase as an expression, then evaluate when x=5: 6 more than the product of 8 and a number x?

Answer 1

`46`

Explanation:

First, we must write the mathematical form for "the product of 8 and a number x":

`8 xx x`

Then "6 more than this" would be:

`(8 xx x) + 6`

So, to evaluate for `x = 5` we substitute `5` for `x` and calculate:

`(8 xx 5) + 6 -> 40 + 6 -> 46`
