Which number is NOT in the solution set of x + 6 < 14?
A.)3
B.)5.
C.)7.
D.)11

11

Step-by-step explanation: To determine which number is not a solution for the inequality, first begin by substituting in 3 for x.

So we have (3) + 6 < 14.

(3) + 6 is 9 and we can see that 9 < 14.

This means that this is a solution so we need to continue.

Now substitute a 5 in for x.

So we have (5) + 6 < 14.

(5) + 6 is 11 and we can see that 11 < 14.

This means that this is a solution so we need to continue.

Now substitute a 7 in for x.

So we have (7) + 6 < 14.

(7) + 6 is 13 and we can see that 13 < 14.

This means that this is a solution so we need to continue.

Now substitute an 11 in for x.

So we have (11) + 6 < 14.

(11) + 6 is 17 and we can see than 17 < 14.

Notice that the inequality 7 < 14 is not a true statement however because 17 is greater than 14, not smaller. This means that 11 is not a solution.

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
