Answer:
The sides of the original rectangular prism have been increased by a scale factor of 4
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z----> the scale factor
x---> volume of the increased rectangular prism
y---> volume of the original rectangular prism

substitute

-----> the scale factor
therefore
The sides of the original rectangular prism have been increased by a scale factor of 4
The best method here is to plug in so plug in -1 (-1)+5+3(-1)=1 so the answer is A

Answer:
A cage holds 6 black cats and 9 white cats, if two cats escape what is the probability of both cats being white?
Step-by-step explanation:
This involves two events, each with their own probability. Because both the first AND the second have to happen for this problem, you will MULTIPLY the wo individual probabilities.
Total cats = 15, White cats = 9
Probability first escaped cat is white = 9/15
One white cat has now escaped, so we now have Total cats = 14, White cats = 8
Probability second escaped cat is white = 8/14
Now MULTIPLY because this is an AND probability problem. (9/15)(8/14) = 72/210 = 12/35
