Answer:
7 4 9
5 6 1
3 2 8
Step-by-step explanation:
..........................
The answer to the question is c
Follow the a² + b² = c² formula
The hypotenuse always equal the c
a and b can be the other two numbers and are interchangeable
plug in 5 and 6 into a and b
(5)² + (6)² = c²
simplify
25 + 36 = c²
add
c² = 61
isolate the c, root both sides
c² = 61
√c²= √61
c = √61
Roots are Irrational numbers, and so D) irrational number should be your answer
hope this helps

Answer:
thats not a question, that is a statement
Step-by-step explanation:
Answer: The equations are
6x - 6y = 9
4x + 4y = 9
Step-by-step explanation:
Let x represent the speed of the row boat in still water.
Let y represent the speed of the current.
Dana can travel 9 miles in her rowboat in 6 hours against the current. This means that the total speed at which she travelled is
(x - y) miles per hour.
Distance = speed × time
Distance travelled against the current is expressed as
9 = 6(x - y)
6x - 6y = 9
With the current, it takes 4 hours to row the same distance. This means that the total speed at which she travelled is
(x + y) miles per hour.
Distance travelled with the current is expressed as
9 = 4(x + y)
4x + 4y = 9
