Answer:
A. When x = 3, both expressions have a value of 30.
Step-by-step explanation:
The first expression is 4(x+3)+2x
The second expression is 6(x+2).
When we substitute x=3 into the first equation, we get:
When we substitute x=3 into the second expression we get:
This proves that the two expressions are equivalent.
The correct choice is A
Mean is the average. To find the mean of a data set, you have to add all the numbers and divide the sum by the amount of numbers you added.
<em>In this equation, you have 8 numbers. That means you will be dividing by 8. </em>
The first thing you need to do is add all the numbers. Add:
Now that you have added all the numbers and got the sum, divide by 8. Remember that you will be dividing by 8 since you added 8 numbers.
Divide:
The mean is 66
