Your answer is 26,453
Although I don't feel as if this is a homework question, I will still show the work.
Work:
Step 1: 999 + 999 = 1,998
Step 2: 1,998 + 999 = 2,997
Step 3: 2,997 + 23,456 = 26,453
Hope I was able to help! :)

ok
Step-by-step explanation:
Answer: Choice E
multiply to give a*c and add to get b
===========================================
This is known as the AC factoring method based on how you multiply the first and last coefficients (a and c) and use that product to figure out which factors add to the middle coefficient.
---------
An example:
6x^2 + 35x + 50
We have a = 6, b = 35, c = 50
Multiply a and c and we get: a*c = 6*50 = 300
We need to find factors of 300 that pair up and add to 35
Through trial and error you should find,
15 * 20 = 300
15 + 20 = 35
The two numbers are therefore 15 and 20.
So we break 35x into 15x+20x and use the factor by grouping method
6x^2 + 35x + 50
6x^2 + 15x + 20x + 50
(6x^2 + 15x) + (20x + 50)
3x(2x + 5) + 10(2x + 5)
(3x + 10)(2x + 5)
We see that 6x^2 + 35x + 50 factors to (3x + 10)(2x + 5)
Use the FOIL method or the box method or distribution to help see that (3x + 10)(2x + 5) expands back to 6x^2 + 35x + 50.
Answer:
The correct option is;
x = 1
Step-by-step explanation:
The parameters given are;
Location of circle center = 1 on the x axis
Radius of circle = 1
Required operation on circle = Revolving to create a sphere
To form a spherical shape by the rotation of a circular figure involves rotating the circular figure about a line passing through the center of the circle
Therefore, to form a sphere, the circle should be about a line that passes through x = 1
Hence, the circle should be rotated about the line x = 1.
