<h3>
Answer: Choice C) 9m^8</h3>
============================================================
Explanation:
Each side of the square is the same, so we have length = width in this case.
Length = 3m^4
Width = 3m^4
Area = (length)*(width) = (3m^4)*(3m^4) = (3*3)*(m^4*m^4) = 9m^8
Note how m^4*m^4 leads to m^8. We add the exponents.
The general rule is a^b*a^c = a^(b+c).

Answer:
I don't know D
Step-by-step explanation:
but why is this in the mathematics section
1. We assume, that the number 43 is 100% - because it's the output value of the task. Also that x is the value that we are looking for.
So you write down 100%=43
Next x% equals 18 of the output value.
so you write it down as x%=18
Now we have two simple equations:
Which is 100%=43 and x%=18
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=43/18
Now we just have to solve the simple equation.
Solution for 18 is what percent of 43?
(100/x)*x=(43/18)*x - we multiply both sides of the equation by x
100=2.38888888889*x - we divide both sides of the equation by (2.38888888889) to get x
100/2.38888888889=x
41.86=x
x=41.86
now we have:
18 is 41.86% of 43
Answer:
32 years
Step-by-step explanation:
fist find how much of 6750 is 6.25%
6750 * .0625 = 421.875
then use trial and error until u get the number u want
421.875 * 10 = 4218.75 + 6750 = 1096875 NO
421.875 * 20 = 84375 + 6750 = 151875 NO
421.875 * 30 = 12656.25 + 6750 = 19406.25 NO
421.875 * 31 = 13078.125 + 6750 = 19828.125 NO
421.875 * 32 = 13500 + 6750 = 20250 YES
