A perfect square must be hidden within all of those radicands in order to simplify them down to what the answer is.

.

.

. The rules for adding radicals is that the index has to be the same (all of our indexes are 2 since we have square roots), and the radicands have to be the same. In other words, we cannot add the square root of 4 to the square root of 5. They either both have to be 4 or they both have to be 5. So here's what we have thus far:

. We can add

and

to get

. That means as far as our answer goes, A = 72 and B = 4, or (72, 4), choice a.
Good morning to you too! I will check them and try my best to answer them. If I cannot, I am sorry. Have a nice day! I hope you pass!

Determine which has a better value
First, we calculate the unit rate of both.

For the family size:


For the mega size:


<em>By comparing the unit rates, the mega size has a better value because it costs cheaper per unit rate</em>
Answer:
infinitely many solutions
Step-by-step explanation:
12x-10=12x-10
12x=12x

The range of possible values of the measurement is:
[45.97cm, 48.03cm]
<h3>Which is the possible range for the measurement?</h3>
Here we have the measurement:
measurement 47 cm ± 2.2%
The 2.2 percent of 47cm is:
47cm*( 2.2%/100%) = 47cm*(0.022) = 1.034 cm
Then the minimum of the measurement is:
47cm - 1.034cm = 45.97cm
The maximum of the measurement is:
47cm + 1.034cm = 48.03cm
we conclude that the correct option is the second one:
[45.97cm, 48.03cm]
