Answer:

The factors of 41 are 1 and 41. It is a prime number because the only factors are one and itself

1, 14 are the factors the 41 because nothing else equals 41. 41 is a composite number because again, nothing else other than 41 and 1 equal 41.
Hope this helped:)

Which statement describes if there is an extraneous solution to the equation √x-3 = x-5? A. there are no solutions to the equati

Brrunno [24]

Remember that an extraneous solution of an equation, is the solution that emerges from solving the equation but is not a valid solution.

Lets solve our equation to find out what is the extraneous solution:
 $\sqrt{x-3} =x-5$
$(\sqrt{x-3})^2 =(x-5)^2$
$x-3=x^2-10x+25$
$x^2-11x+28=0$
$(x-4)(x-7)=0$
$x-4=0$ and $x-7=0$
$x=4$ and $x=7$

So, the solutions of our equation are $x=4$ and $x=7$ . Lets replace each solution in our original equation to check if they are valid solutions:
- For $x=7$
$\sqrt{x-3} =x-5$
$\sqrt{7-3} =7-5$
$\sqrt{4} =2$
$2=2$
We can conclude that 7 is a valid solution of the equation.

- For $x=4$
$\sqrt{x-3} =x-5$
$\sqrt{4-3} =4-5$
$\sqrt{1} =1$
$1 \neq 1$
We can conclude that 4 is not a valid solution of the equation; therefore, 4 is a extraneous solution.

We can conclude that the correct answer is: D. the extraneous solution is x = 4

PLEEEEEEEAAAAAAAAAASSSSSSSSSEEEEEEE a wee this quickly How did he get answer A

Simora [160]

Answer:

To get answer A, Dave took 47*5 = 235

Step-by-step explanation:

There are 147 containers that contain 5 gallons each. We need to multiply to find the total number of gallons.

total number of gallons = containers * number of gallons per container

= 147* 5 gallons per container

=735 gallons

To get answer A, Dave took 47*5 = 235
