TIMED The model shows the addition expression 18 + 12
One expression that is equivalent to this sum is

3 + 6 + 4
3(6 + 4)
3 + 6(4)
3(6) + 4

3(6 + 4)

Step-by-step explanation:

We have a model that is showing a certain expression, while knowing that the expression it's showing is "18 + 12"

To solve, all we have to do is simplify the answers. Do as following :

A. 3 + 6 + 4

This is already incorrect, the answer is split into three numbers and we are only looking for two, even if you try combining the numbers to make 2 terms, you will not get 18 + 12.

B. 3(6 + 4)

This is correct, the answer is a distribution problem that when solving :

(3(6) + 3(4))

18 + 12

Gives you what the question is asking for.

C. 3 + 6(4)

This is incorrect, when you distribute 6 and 4, you get 24. Leaving you with the expression 3 + 24.

D. This is incorrect, when you distribute 3 and 6, you get 18. Leaving you with the expression 18 + 4.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
