Answer:
2
Step-by-step explanation:
To figure this out, you must use the triangle inequality theorem. It says that the sum of 2 sides of the triangle should be more than the third side. If you add 8 and 12, you get less than 24 but if you add 12 and 24 or 8 and 24, you will get more. So, there are only 2 triangles! I hope this helps!
Answer: y=6
Step-by-step explanation:
Data: y=3 and x=12

The sum means that Eric is 3.3 m above sea level.
<h3>What is an addition expression?</h3>
This is a way of taking the sum of two or more expressions.
Given the following parameters
- The distance while descending = -13.7 meters
- The distance while ascending = +15.2 meters
An additional expression in the form of Descent + Ascent to represent this situation will be -13.7 + 15+ 2
<u>Calculate the sum:</u>
Sum = -13.7 + 15+ 2Sum = 3.3 meters
Hence the sum means that Eric is 3.3 m above sea level.

Answer: c) rotation of 180° & shift right 1 unit and down 2 units
<u>Step-by-step explanation:</u>
Rotation of 180° changes the signs of x and y
(x, y) → (-x, -y)
Shift right one unit adds 1 to x, Shift two down subtracts 2 from y
(-x, -y) → (-x + 1, -y - 2)
<u> (x, y) </u> <u> (-x + 1, -y - 2) </u>
(-1, -2) → (2, 0)
(-4, -1) → (5, -1)
(-4, -3) → (5, 1)
