Answer:

B. x^2(4x^2 + 2x -9) -3x(4x^2 + 2x - 9)

Step-by-step explanation:

The distributivity establish that in order to multiply these two polynomials, first you have to multiply x^2 by every element in  4x^2 + 2x - 9 and then multiply -3x by every element in 4x^2 + 2x - 9 as well.

That is exactly what the option B. says, since

in the expresion x^2(4x^2 + 2x - 9) - 3x(4x^2 + 2x - 9) x^2 is being multiplied  by every element in  (4x^2 + 2x - 9) and also -3x is being multiplied by every element in  (4x^2 + 2x - 9).

Weights of female cats of a certain breed are normally distributed with mean 4.1 kg and standard deviation 0.6 kg.
Diano4ka-milaya [45]
The proportion is 0.4401.

We find z-scores that correspond with both ends of this interval.  Z-scores are given using the formula:

z=\frac{X-\mu}{\sigma}

For the lower end, 

z=\fracc{3.7-4.1}{0.6}=\frac{-0.4}{0.6}=-0.67

The proportion of scores to the left of this number is 0.2514.

For the higher end, the z-score is

z=\frac{4.4-4.1}{0.6}=\frac{0.3}{0.6}=0.5

The proportion of scores to the left of this number is 0.6915.

To find just the proportion of scores between these two, we subtract;

0.6915-0.2514 = 0.4401.

The sum of three consecutive even integers is –78. What are the integers?
Korvikt [17]

Answer:

the three even integers are -28, -26 and -24.

Step-by-step explanation:

Represent the three numbers as follows:

n

n+2

n+4

Their sum is n + n+2 + n+4 = -78.

Combining the n terms, we get:

3n + 6 = -78, or

3n = -84

Then n = -84/3, or n = -28.

Then the three even integers are -28, -26 and -24.
