Answer:
hii there
your answer is here
(PQ)2 + (QR)2 = (PR)2, because 9 + 16 = 25
PQ + QR = PR, because 9 + 16 = 25
(PQ)2 + (QR)2 = (PR)2, because 52 + 32 = 42
PQ + QR = PR, because 52 + 32 = 42

- Reading a Cartesian Plane
- Identifying Coordinates
Step-by-step explanation:
The meaning of f(2) is x = 2. The question is asking us to find the y-value when x = 2.
According to the graph, when x = 2, y is somewhere between 8 and 10. The graph looks like it intersects right in the middle of those 2, so the y-value when x = 2 would be 9.
Therefore, f(2) = 9.

===========================================================
Explanation:
Think of a table that has 2 rows and 3 columns.
Each row represents a different math class (either Algebra or Geometry).
Each column represents a different foreign language class (French, Spanish or Latin).
This table has 2*3 = 6 cells inside. Each cell represents a different combination of classes possible.
In short, all we have to do is multiply the number of classes for each subject.
Answer:
Simplifying
5(6.2a + 9.8) = 18
Reorder the terms:
5(9.8 + 6.2a) = 18
(9.8 * 5 + 6.2a * 5) = 18
(49 + 31a) = 18
Solving
49 + 31a = 18
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-49' to each side of the equation.
49 + -49 + 31a = 18 + -49
Combine like terms: 49 + -49 = 0
0 + 31a = 18 + -49
31a = 18 + -49
Combine like terms: 18 + -49 = -31
31a = -31
Divide each side by '31'.
a = -1
Simplifying
a = -1
