Answer:
x = 3
< D = 26
< E = 54
Step-by-step explanation:
I did the math
The coach can select the captain in 20 ways (i.e. from all the available 20 players), and he can select the co-captain in 19 ways (i.e. after selecting the captain, there will be 19 people left).
Therefore, the coach can select the captain and the co-captain in 20 x 19 = 380 ways.
Answer:
sure
Step-by-step explanation:
The product of a negative integer and a positive integer is a negative integer. The product of two positive integers or two negative integers is a positive integer. That means if you multiply two OF the same sign numbers, the product is always positive. SAME.

Answer:</h3>
x = -5/2
<h3>Explanation:</h3>
<u>Given</u>
(2x+1)/(x-2) + 4/x= -8/(x^2-2x)
<u>Find</u>
x
<u>Solution</u>
We note that the denominators in this equation are x and x-2. The solution set must exclude these values, as the equation is "undefined" for those values of x.
__
Multiply by x(x-2)
x(2x+1) +4(x-2) = -8
2x² +5x = 0 . . . . . . . . . . add 8, eliminate parentheses
x(2x +5) = 0
The solutions are the values of x that make these factors zero:
x = 0 . . . . must be excluded
x = -5/2
The solution to the equation is x = -5/2.
