x+2

Step-by-step explanation:

x+2

If x = –2 is a zero, then x + 2 = 0, so x + 2 is a factor. Similarly, if x = 1/3 is a zero, then x – 1/3 = 0, so x – 1/3 is a factor. By giving me two of the zeroes, they have also given me two factors: x + 2 and x – 1/3.

What is 20% of 5 Please Help
Softa [21]
Hello there!

Start by asking yourself:"How to find the percentage of a number?"

We need to use the equation y = P% * x

In this case, the y is 20%

Y = P% * X

Y = 20% * X

Now we need to convert the percentage to decimal

P = 20%/100

P = 0.2

Then go back to the equation

Y= 0.2 * 5

Y = 1

The answer is 1

I hope the steps are easy to understand and hopefully the answer helps!

As always, I'm glad to help you today!

kupik [55]

Answer:

let the blank be x

2 + 900 + 4,000 +50,000 + 10 + x = 354912

x + 54912 = 354912

x + 54912-54912 = 354912 - 54912

x = 300,000

Which of the following is the surface area of the right cylinder below?
Evgen [1.6K]
The formula for the surface area of a right cylinder is 2πrh + 2πr^2. r is the radius, and h is the height.


In this instance, the radius is 4, so plug that in for r. (I.E. Replace r with 4).


The formula is now 2π4h + 2π4^2.


Next, plug in the height, 8 for h.



Now we have 2π4(8) + 2π4^2, which is approximately 301.59.


The surface area is 301.59. (Unit of measure was not specified)
