Answer:
Nick has to work 8 hours
Step-by-step explanation:
Nick makes 9 works x
Julia makes 12 works 6
first find out how much Julia makes you can do that by multiplying 12 by 6 witch = 72
and we know we are trying to find how many hours Nick needs to work to equal Julia so we knew they are equal
so we have 9X=72
we just have to solve...
divide 72 by 9
leaving use with X=8
You would think it was 3 * 12 = 36. Not so. All polygons have to be broken down into some figure that will give 2 dimensions that are at right angles to each other. That would mean that
d1 * d2 = Area for the small polygon
3d1 * 3d2 = area of the larger polygon
What that means is that the area of the larger one is 9 times the smaller one.
Area large = 12 * 9 = 108 square units. <<<<< answer.
If you find this hard to be leave try it with a square.
Suppose you have a square (the small one) that is 3 cm by 3 cm
The small one has an area of 3*3 cm^2 = 9 cm
Now you have another square that is 3 times larger. That means that each side is 3*3 = 9
So s = 9
Area = s^2
Area = 9^2 = 81 cm^2
81 is 9 times larger than 9 just as you would think.
Answer:
13=u
Step-by-step explanation:
54/4 = 13
If 
then complex number 
is a root of cubic polynomial.
If polynomial has real coefficients, then conjugated 
is also a root of polynomial.
Then the polynomial will be of a form
Since 
then
Therefore,
