4x^2 - 9y^6 <br> what patterns can be used ?<br> please and thank you !!!
S_A_V [24]

Answer:

<em>B. (U+V)(U-V)</em>

Step-by-step explanation:

<u>Factoring</u>

The given expression is:

4x^2-9y^6

It should be noted that both terms are perfect squares:

(2x)^2=4x^2

(3y^3)^2=9y^6

Since it's a difference of squares, we need to use the following pattern to factor the required expression:

(U^2-V^2)=(U+V)(U-V)

Thus, the answer is

B. (U+V)(U-V)

Which function is quadratic?
PilotLPTM [1.2K]

Answer:

step 1. A, B,D are incorrectly written as these are not all coordinates. they must be written (x, y)

step 2. so the question becomes is C a quadratic

step 3. The x values must be evenly spaced. the x values are evenly spaced by a difference of 4

step 4. write out the y values: -126, -14, 2, 18

step 5. write out the differences: 140, 16, 16

step 6. write out the differences: -124, 0.

step 7. after doing this twice the numbers nust be the same for this to be a quadratic which they aren't

step 8. C is not a quadratic.

Suppose that there are 20 numbers in a data set and that they are all different. How many of the values in this data set are bet
ohaa [14]

Answer:

4

Step-by-step explanation:

Since the first quartile is at 25%, 25% of 20 is 5. The median is the 50% mark of the set, and 50% of 20 is 10. So, there are 4 numbers between the 5th data point and the 10th, which are the 6th,7th,8th, and 9th data points.
