A.) 120
The variance is the range of a data set, which shows how spread out numbers are. To get the variance, we take the last number and subtract it from the first number. 160-40=120. Therefore, there is 120 numbers between 40 to 160.
If you would like to solve (2x - 6) * (3x^2 - 3x - 6), you can do this using the following steps:
(2x - 6) * (3x^2 - 3x - 6<span>) = 2x * 3x^2 - 2x * 3x - 2x * 6 - 6 * 3x^2 + 6 * 3x + 6 * 6 = 6x^3 - 6x^2 - 12x - 18x^2 + 18x + 36 = 6x^3 - 24x^2 + 6x + 36

The correct result would be <span>6x^3 - 24x^2 + 6x + 36.</span>
The answer is 4. a term is a group of numbers and variables separated by adding or subtracting. so the first 4 terms 3x3y,5x2,-4y,z all have a variable in them.
Answer:
14
Step-by-step explanation:
AT/TB = AV/VC
5/7 = 10/VC
VC = 14
Hey, Yeah the answer is 9 because
1/3(9)=12-9
3 = 3
They're equall
