Answer:
The sides of ∆ABC are 30 units, 40 units, and 60 units long.
The perimeter will be = 
units
Given is that ∆ABC and ∆XYZ are similar and the corresponding sides of ∆XYZ are 'r' times as long as the sides of ∆ABC.
So, perimeter of ∆XYZ will be : 
units.
----------------------------------------------------------------------------------------
The area of ∆ABC is n square units, so area of ∆XYZ will be :
= 
= 
square units.
The correct answer would be choice A: 1.
When 3 coins are flipped, there are 8 possible outcomes.
0 Tails = 1 ways
1 Tails = 3 ways
2 Tails = 3 ways
3 Tails = 1 ways
If you add up all the different tails, you could get 12 tails. Divide 12 by 8 and you have 1.5 which is the average number of tails you could expect to get by flipping 3 coins.
Answer:
Step-by-step explanation:
When we factor expressions, we look for factors within the terms that are alike, or in other words, we look for common factors. Here, 
and 
only have one common factor: 
. Therefore, to factorize this expression, divide both terms by .
Now, we've "carried" out of the expression and have therefore factored it.
I hope this helps!
