Answer:

! means factorial . For example 3! (factorial 3) = 3*2*1 = 6

Answer to 14C3 is 364

Step-by-step explanation:

14! = 14*13*12*11*10*9*8*7*6*5*4*3*2*1

14C3 = 14*13*12*11*10*9*8*7*6*5*4*3*2*1 / 3*2*1 * 11*10*9*8*7*6*5*4*3*2*1

= (14*13*12) / 3*2*1

= 14*13*2

= 364

Find the solution of 3 times the square root of the quantity of x plus 5 equals negative 9, and determine if it is an extraneous

zysi [14]

<u>Answer:</u>

x = 4, it is an extraneous solution.

<u>Step-by-step explanation:</u>

Translating the given statement, we get the following equation:

$3\sqrt{(x+5)} =-9$

Dividing both sides by 3, we get:

$\sqrt{(x+5)} =-3$

Now we will take square on both sides of the equation to get rid of the square root to get:

$(\sqrt{(x+5)} )^2=(-3)^2$

So we are left with:

$x+5=9\\\\x=9-5\\\\x=4$

Therefore, the solution is 4.

Also, it is an extraneous solution because the equality is not met by substituting x = 4 in the original equation:

$3\sqrt{(4+5)} =-9$

$3\sqrt{(9)} =-9$

$3(3) =-9$

$9\neq -9$
