4 0

Answer:

(x + 2)² = 8

Step-by-step explanation:

To complete the square, write the equation standard form.

-4 + 4x + x² = 0

x² + 4x - 4 = 0

Take the middle term 4x and divide the coefficient in 2 and square it. Here it is 4/2 = 2. 2² = 4. Add 4 to both sides.

x² + 4x + 4 - 4 = 0 + 4

(x + 2)² - 4 = 4

(x + 2)² = 8

HELP ME PLEASE
Zina [86]

Answer:

π(5²)(13)+⅓π(5²)(12)

Step-by-step explanation:

You can find the volume of the cylinder by:

V=πr²h

which is V1=π(5²)(13)

and the volume of the crooked cone by:

⅓πr²h

which is V2=⅓π(5²)(12)

and you need the volume of the whole shape. you can find by adding V1+V2

Need help. asap. also need an explanation for the problem. :)
Maurinko [17]

Answer:

124858

Step-by-step explanation:

The first 4 digits are simple, you multiply the first digit of the equation by the 2nd digit and then for the other 2 you multiply the first digit of the equation by the 3rd digit.

6 + 2 + 8

6 * 2 = 12

6 * 8 = 48

Then the last 2 digits are the sum of the products of the 1 and 2 and 1 and 3 and subtract it by the 2

12 + 48 = 60

60 - 2 = 58

Put them together
