Answer:
- 24 - 5x
Step-by-step explanation:
1) Remove Parentheses
-2 - 3x - 6 - 9 - 7 + x - 3x
2) Collect like terms
( -2 - 6 - 9 - 7) + (-3x+x-3x)
3) Simplify
Start at (-2, 4) and draw a line that goes right once and down 3 times then repeat
Answer:
39 (the first option listed among the possible answers)
Step-by-step explanation:
Recall that the mean is the same as the average of the numbers you have listed, that is the addition of all divided by the number of entries you use:
mean =
Therefore, rounding to the nearest integer, our answer s: 39
This is a quadratic trinomial.
We know this because all terms written with the term x^2 as the lead variable, is called quadratic. The second part of the naming is based on the numbers in the term. Since there are 3, we use trinomials.
2(3) + 3(4) + 4(16) + 5(22)
Multiply
6+12+64+110
Add
192
Divide by the total amount of testers
192/((3+4+16+22))
192/45
Divide
About 4.22
Because all the scores are whole numbers, the average score is a 4
I hope this Helps!
