The mean is the average of the numbers. To obtain it, you add all the numbers together and divide by the number of numbers. So:

8+3+3+7+4= 25

25:5= 5

So the answer is: the mean is 5.

D₁ vide using x² - 2x² 2× +3× -5 by ×-3 using synthetic division.

Vaselesa [24]

Answer:

Step-by-step explanation:

I think you are trying to use synthetic division for

$x^{4} -2x^{3} -2x^{2} +3x-5$ divided by x-3

First

x -3 = 0 , make it equal to 0 and add 3 to both sides

x = 3

Then we write all the coefficients and continue with

a pattern of multiply by 3 and add to the next coefficient.

40•(420:x-37)=200 помогите решить уравнение

miv72 [106K]

40•(420:x-37)=200 означает $40(\frac{420}{x}-37)=200$

разделите обе стороны на 40

$\frac{420}{x}-37=5$

добавить 37 с обеих сторон

$\frac{420}{x}=42$

умножить обе стороны на х
420=42x

разделите обе стороны на 42
10=x
x=10
