Answer:
A. 2x + 1
Step-by-step explanation:
6x³ - 15x² - 9x
3x (2x² - 5x - 3)
3x (2x² + x - 6x - 3)
3x (x (2x + 1) - 6x - 3)
3x (x (2x + 1) - 3 (2x + 1))
= 3x <u>(</u><u>2</u><u>x</u><u> </u><u>+</u><u> </u><u>1</u><u>)</u> (x - 3)
one of the factor of the complete factorization is <u>A</u><u>.</u><u> </u><u>2</u><u>x</u><u> </u><u>+</u><u> </u><u>1</u>
Answer:
Step-by-step explanation:
Given the inequality solved by a student expressed as:
-6v>42
To get v, follow the simple steps
Step 1: multiply both sides by -1
-6v>42
-1(-6v)<-1(42)
6v < 42 (Note that when you multiply both sides of an inequality by a negative sign, the inequality sign will change)
Step 2: Divide through by 6
6v < 42
6v/6 < 42/6
v < 7
Hence the range of values of v are the values of v less than 7
Since we are not given the options, you can compare the solution given with that of the student to figure out the error. The major error that may happen is the different not changing the inequality sign after multiplying or dividing with a negative value as shown.

Answer:
2 < x <7 I got the same question has you
Step-by-step explanation:
.....
Mrs. Potter’s class was more consistent because their standard deviation of 3 points was lower.
<h3>What is a
statistical dispersion?</h3>
A statistical dispersion is also referred to as degree of dispersion and it can be defined as a measure of the extent to which a numerical value (data) is likely to vary about a mean or an average value.
In Mathematics, there are four measures of dispersion for a data set and these include the following:
In this scenario, we can infer and logically conclude that Mrs. Potter’s class was more consistent than Mr. Jones class because their standard deviation of 3 points was lower.
