Step-by-step explanation:
(given)
Let us consider :
= 
= 
=
=
=
Now, by substituting the above considerations in the above equation, we get:
where,
1
then it follows
n = 20
r = 4
then no. of solutions for the eqn = 
= 
= 10626
Answer :
no. of solutions for the eqn 10626
Hey there!
a + 2 = 10
SUBTRACT 2 to BOTH SIDES
a + 2 - 2 = 10 - 2
CANCEL out: 2 - 2 because that gives you 0
KEEP: 10 - 2 because that helps solve for the a-value
10 - 2 = a
10 - 2 = 8
Answer: Option C. a = 8
Good luck on your assignment and enjoy your day!

Answer:
Two consecutive integers are of the form
x and x + 1
Their product is equal to 56
x(x + 1) = 56
Solve and find the two numbers x and x + 1. The above equation may be written as follows
x2 + x - 56 = 0
Factor and solve
(x - 7)(x + 8) = 0
solutions: x = 7 , x = -8
x= - 8 is not valid since the number sought must be positive. Hence
x = 7 and x + 1 = 8 are the two consecutive numbers.

Answer: Average discharge at the mouth of the Amazon River in 1 hour =
cubic feet
Average discharge at the mouth of the Amazon River in 1 year=
cubic feet[/tex]
Step-by-step explanation:
Given : The average discharge at the mouth of the Amazon River =4,900,000 cubic feet per second.
i.e. The average discharge at the mouth of the Amazon River in 1 second= 4,900,000 cubic feet
Since 1 hour = 3600 seconds
Then , the average discharge at the mouth of the Amazon River in 1 hour =
cubic feet
Since , there are 2080 hours in a typical year.
Then, the average discharge at the mouth of the Amazon River in 1 year=
cubic feet
