i think:

\(\frac{15!}{6!*4!*2!*3!} = 6306300\)

Thank you Guest and CPhill ! :)

\(V_{rectangle}=L\times W\times H \\ S_{rectangle}=2(lw + lh + wh) \)

it s only possible if

\(H=W\)

So you have length=12 and Volume=324:

\(324=12\times W \times H \\ W=\sqrt{27}\\ H=\sqrt{27}\)

\(S_{rectangle}=2(12\sqrt{27}+12\sqrt{27}+\sqrt{27} \times\sqrt{27})=303.4153162899183302679522731768456208397639565486948104400\dots\)

eh stupid me :(

i can t understand if the long car took 2 places and there are 5 spots and 5 cars. You can only place 4 cars on the parking lot it s 4! and you can change places of the car 5 times because you have 5 cars :

4!*5=120

i am bewildered :/

sqrt(-100) = 10i

i-imaginary

you can t put any negative number into square root !

y=2x-4

Here s the graph:

I think:

37.8-25.0=12.8 mL

66.9/12.8 = 5.2265625 g/mL

do you mean that ?

\(\pi^2=9,86960440109 \dots\)

x = –4

–(x)=-(-4)    two minuses will give you plus

-x=4
