Answer:
2
Step-by-step explanation:
8 - 20 = -12
-2 - 4 = -6
-12/-6 = 2
Answer: The value of x is 3.
Step-by-step explanation:
Since we have given that
10,11, 12 and x
Average of above numbers = 9
As we know that
Average is given by
Hence, the value of x is 3.
The last one is the correct answer!! nothing that is dilated can be congruent to another triangle.
The smallest value it could be is 4 and the largest value it could be is 10.
The triangle inequality theorem states that any two sides of a triangle must have a sum greater than the third side. Given the two sides we have, 7 and 4, the sum would be 11; this would mean that the missing side could be no more than 10.
If we take the unknown side and the smallest one we're given, we would have the inequality
n+4>7
Subtracting 4 from both sides we would have n>3. That means it would have to be the next integer up, which would be 4.
Okay so you have to add up 15 and 11 and 4 so your answer is y=30
