Dan factored x^2+121 into (x+1-11)

babunello [35]

Answer:

Your question is a little unclear. If you are just trying to factor x² + 121, it's prime. (can't be factored using real numbers).

Step-by-step explanation:

The difference of two squares is a special form. a² - b² = (a+b)(a-b).

But, the sum of two squares is prime. a²+ b² cannot be factored.

suter [353]

Answer:

Option C is the answer.

Step-by-step explanation:

The possible advantage of offering rewards or incentives to increase response rates is :

A possible advantage of offering rewards or incentives to increase response rates is that respondents put more effort into completely and accurately answering the survey questions because they feel obligated.

---------------------------------------------------------------------------------------------

The disadvantage can be a biased result or outcome.

Because suppose if it is a product based survey and you are offered some reward for answering the questions, then it is possible that respondents answers are product driven, to get the reward.

Lydias hotel room number has three digits.The hundreds digit has a value of 40 Tens.The Tens digit is greater than 6. Which coul

stiks02 [169]

Any 3 digit number can be expressed in the form of:

$(a*100)+(b*10)+(c*1)$

Where $a, b, c$ represent any natural number from 0 to 9.

We are told the hundreds number (this means $a*100$ in the expression above) is equal to the value of 40 tens, 40 tens is 400. Then, we know the digit in the tens is greater then 6, this means $b>6$ in the expression above.

So, there are multiple numbers the room number could be, namely:

$400+(b*10)+(c*1)\\$

where $b$ can be 7, 8, or 9; and $c$ can be 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. So, there's 30 possible room numbers Lydia may be.
