2x^2+8x+3
(x-12)(X+2)
x-3

Solution,

3x^2+5x-6+(-x^2+3x+9)

 = 3x^2+5x-6-x^2+3x+9

 = 3x^2-x^2+5x+3x-6+9

 =2x^2+8x+3

 2. x^2-10x-24

 = x^2-(12-2)x-24

 = x^2-12x+2x-24

 = x(x-12)+2(x-12)

 =(x-12)(X+2)

3. 3x^2-9x

 take the common,

 = 3x(x-3)

Answer:

Option OD - 9

Step-by-step explanation:

Given : On the cardiac ward of a local hospital, there are 7 nursing assistants. The seven assistants have 7, 8, 5, 9, 10, 10, and 14 patients, respectively, that they assist.

To find : What is the average number of patients per nursing assistant?

Solution :

The average number of patients per nursing assistant is given by the division of sum of number of patients by total number of nursing.

So, $\text{Average} =\frac{\text{Sum of patients}}{\text{Number of assistants}}$

$\text{Average} =\frac{7+8+5+9+10+10+14}{7}$

$\text{Average} =\frac{63}{7}$

$\text{Average} =9$

Therefore, The average number of patients per nursing assistant is 9.

So, Option OD is correct.
