Answer:

Step-by-step explanation:
Given
From Figure
Sides of Triangle

Now, using concept
Perimeter of triangle = Sum of the sides of triangle
So,
Perimeter of triangle = 
Adding
and
, so,
Perimeter of triangle = 
This can be written as
Perimeter of triangle = 
Adding 15 and 10,
Perimeter of triangle = 
So, the correct choice is = 
Hope this helps.
Assuming that this particular type of question is a system of equations one. More specifically linear equations, you would simply substitute one of the equations into the other one. Then upon doing so, plug in the x and y coordinates for the point into the x and y variables of the equation and then see if it is a solution, by checking if the left hand side of the equation equals that of the right hand side of the equation.

Answer:
(1/6)^3 = 1/216, these events are independent.
Step-by-step explanation:
What happens in one roll has no effect on the other rolls, so these events are independent. The probility of any roll outcome is 1/6 since there are 6 sides. Since you want to roll a 6 AND a 5 AND a 4 you have to multiply the probabilities.
Answer:
2
Step-by-step explanation:
x÷3 dư 1-->x=3a+1
y÷3 dư 2-->y=3b+2
x×y=(3a+1)×(3b+2)
=9ab+6a+3b+2
Mà 9ab, 6a, 3b chia hết cho 3, 2 chia 3 dư 1
==>x×y chia 3 dư 2
