Answer:
'Twice the sum of a number and 5' can be translated into variable expression such as:
Step-by-step explanation:
Given the phrase
<em>Twice the sum of a number and 5</em>
First, let us breakdown the English Phrase
Let the number be = n
The sum of a number 'n' and 5 = n + 5
now, twice the sum of a number and 5 can be determined by multiplying (n+5) with 5.

Step-by-step explanation:
3(2x^2 + 4) - 4(x - 6)
= 6x^2 + 12 - 4x + 24
= 6x^2 - 4x + 36
therefore first answer is correct
