Answer:
90 cm, 180 cm, 240 cm
Step-by-step explanation:
Let the lengths of sides of the triangle be 3x, 6x and 8x

Hence, lengths of the sides of the triangle are 90 cm, 180 cm and 240 cm.
Answer:
So for the first one the first ting u have to do is FLIP the equation so---> X-12=y
Then you have to add 12 to BOTH sides----> x-12+12=y+12
<u><em>So your answer for X ----> x=y+12</em></u>
<u><em>For Y on the first equation it is--->y=x-12</em></u> (Just flipped and the sign changed)
For the second equation we are gonna solve for Y first.
The first thing u want to do is divide both sides by -3 so it will look like this
-3y/-3 = 2x/+36/-3
<u><em>So Y will equal-----> -2/3x- 12</em></u>
Now we are going to do the X part
So fist FLIP the equation----> 2x+36= -3y
The add -36 to both sides-----> 2x+36+-36=-3y+-36
Last step you have to divide both sides by 2
So that would be----> 2x/2= -3y-3
<u><em>Your final result will be----> x=-3/2y-18</em></u>
I hope this helped you out (:::::::
Answer: 
Step-by-step explanation:
When any number has a negative exponent, all the negative exponent is doing is flipping the sides.
When we plug -3 in for x we get
.
Now just imagine the -3 in fraction form as
. And all you do now is just flip the sides to get 
And now apply the exponent 2 to the 1 and negative 3.
1 to the power of 2 is just 1
-3 to the power of 2 is 9.
So your answer is 
Answer:
it is sin C
Step-by-step explanation:
The number of three-digit positive integers that have three different digits and at least one prime digit are 7960.
The only two components in prime numbers are 1 and the number itself.
Any whole number greater than one is a prime number.
It has exactly two factors—1 and the actual number.
There is just one 2-digit even prime number.
Every pair of prime numbers is always a co-prime.
The product of prime numbers can be used to represent any number.
Three-digit positive integers that have three different digits and at least one prime digit = 3!*4!*10*9 = 7960
