Answer:
Step-by-step explanation:
Given :The sum of three times a number and 6 is at least 12.
To Find:Write an inequality for the given statement
Solution:
Let n be the number
So, 3 times of a number = 3n
Now Sum of three times of a number and 6 = 3n+6
Since we are given that the sum of three times a number and 6 is at least 12(i.e. equal to or greater than 12)
So, A.T.Q.
Thus an inequality for the given statement: the sum of three times a number and 6 is at least 12 is

Answer:
Step-by-step explanation:
The first step to this problem is to look at the key features of the initial expression given to us. Namely, the middle term.
Notice that it is just . This indicates that the square root terms cancel out, meaning that their signs need to be opposite, but the threes need to have the same, positive sign. This indicates that our answer is option C, but you should always double check by multiplying the expression out to confirm. Here are the steps:
Therefore as we suspected, the answer is C.
