I am confused on number 15, the instructions are at the top.

Answers

You don't have #15 included.  If you meant to put #25, I already answered that.  Here is the solution again though.

#25 is fairly simple.  Plug in -4 and 3 into the equation, and the extraneous root will be the one that does not work.
√(12-(-4)) = √(16) = \frac{+}{}4
Extraneous root in this case is positive four since +4≠-4
√(12-3) = √(9) = \frac{+}{}3
In this case it's negative 3, since -3≠3

What is the sum of 7/22 and 9/22

Answers

 when u have a common a denominator then you just add the numerator that would be 7 and 9. 7 + 9= 16
so ur solution would be 16/22 and then u would simplify by dividing both values by 2.
so the solution is8/11

You need a common denominator. You already have one. So add 7+9=16. Put 16 over 22. That's your answer without reduction.

When you reduce it, divide it by 2 since its an even number.

16/22=8/11

In converting 105 seconds to minutes, what unit (omit the number) would you place in the denominator of your ratio? Use the plural form in your answer. Remember that there are 60 seconds in 1 minute.

Answers

Convert 105 seconds into minutes

60 seconds = 1 minute

105 seconds * 1minute/60 seconds = (105 * 1 minute)/ 60 = 105 min / 60 = 1.75 minutes

The unit that you place in the denominator of your ratio is seconds. This will cancel out the seconds placed in the numerator of 105.
