Answer:
D = √(6 - 9)^2 + (3 + 2)^2]
Step-by-step explanation:
This is an application of the Pythagoras theorem:
D = √ [(x2 - x1)^2 + (y2 - y1)^2] where the 2 points are (x1, y1) and
(x2, y2).
So in this case we have
D = √[(6 - 9)^2 + (3 - -2)^2]
D = √(6 - 9)^2 + (3 + 2)^2]
The most efficient way to solve this problem is isolating the y in the first equation because:
6x + 3y = 27
3y = 27 - 6x
y = 9 - 2x
Since all the numbers have a common factor of 3, it can be easily simplified/reduce.
If you used any other variable, you would have gotten a fraction.
Now that you found y, you can substitute it into the other equation to solve for x.
ANYWAYS, your answer is A
Answer:
Alex's rock
Step-by-step explanation:
Marianne's distance: 15 inches 4 times = 15 * 4 = 60 inches
we can convert Marianne's distance to feet so we can easily compare it to Alex's
12 inches = 1 foot
1 foot/12 inches = 1. We divide by inches and not feet so that the inches cancel out, as can be seen in the calculations below.
60 inches * 1 = 60 inches * 1 foot/12 inches = 5 feet
7 feet > 5 feet

The permutation shows that when one has been cast yet, the different ways that are there to cast Fantine from the 28 women is 28.
<h3>How to calculate the value?</h3>
The different ways that are there to cast Fantine from the 28 women will be:
= 28!/(28 - 1)!
= 28!/27!
= 28
When Fantine has already been cast, the number of ways that are there to cast adult Cosette from the remaining women will be:
= 27!(27 - 1)!
= 27!/26!
= 26
When Fantine and adult Cosette have already been cast, the different ways that are there to cast Éponine from the remaining women is:
= (28 - 2)!/(28 - 2 - 1)!
= 26!/25!
= 25
