Answer:

Question 3 - B

Question 5 - A

Step-by-step explanation:

Question 3

-2(x+6)(x-1)  - answer B

Expand the brackets

(x+6)(x-1) = x² - x + 6x - 6

Simplify = x² + 5x - 6

Now multiply this by -2

-2(x² + 5x - 6) = -2x² + 10x + 12

Question 5

5(x² + 8)(x² - 8) - answer A

First expand brackets.

(x² + 8)(x² - 8) = x⁴ - 8x² + 8x² - 64

8x² cancels out to x⁴ - 64

Now multiply this by 5

5(x⁴ - 64) = 5x⁴ - 320

Hope this has helped. These are the answers I can help with.

What’s the median of 28,45,12,34,36,45,19,20
Ipatiy [6.2K]

Answer:

Median = 31

Step-by-step explanation:

The median is the middle number which comes after arranging the set in ascending order.

Here, the given data is: 28, 45, 12, 34, 36, 45, 19, 20

The data arranged in the ascending order is as follows:

12, 19, 20, 28, 34, 36, 45, 45

Since the number of terms is even, we have two middle numbers, viz.,

28 and 34

The median would be the average of these two.

Therefore, Median = 28+34/2

= 31

The answer is 31.
