(3x² + 2x - 3)(x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

3x²(x - 1) + 2x(x - 1) - 3(x - 1) ← distribute parenthesis

= 3x³ - 3x² + 2x² - 2x - 3x + 3 ← collect like terms

= 3x³ - x² - 5x + 3

The mean of the numbers 22,18,(2y+1),10 and 20 is 15. <br>find the median.

andrezito [222]

Answer:

Median is 18

Step-by-step explanation:

Firstly you have to fine y by using your mean

Therefore, 22+18+(2y+1)+10+20 divide it by the number of the mean that is the sum of the number divide by the total number of the mean which is 5 =15

22+18+2y+1+10+20 over 5 =15

71+y over 5 =15

Cross multiple

71+y=75

y=4

22,18,9,10, 20

Rearrange

9,10,18,20,22

The median is 18
