Answer:

Step-by-step explanation:
It is given that triangle ACB is the preimage and triangle DFE is the image.
We need to find the scale factor of the dilation.
In the given triangles, side AC and DF are corresponding sides.
Therefore, the scale factor of the dilation is
.
It does not represent a polynomial
The answer is 29.4 grams.
How to solve:
1. Convert $15 to quarters. You can do this by multiplying 15 by 4. You use 4 because 4 quarters equal to $1. This will equal to 60 quarters.
2. Multiply both 5.76 and 6.25 by 60 to find the weight of $15 in quarters for today and before 1965.
Today: 5.76 g x 60 = 345.6 grams
Before 1965: 6.25 g x 60 = 375 grams
3. Now that you have the weight of quarters for both time periods, subtract! 375 grams - 345.6 grams = 29.4 grams
The surface area of a shape is basically the sum of all the areas on a shape.
We’ve been given that the side is 17 mm.
An area of a square is A=s^2, in which s means side. So we do 17^2 to get the area of ONE of the squares.
Once we do that we get that the area of 1 square is 289.
Since there are 6 squares we need to multiply 289 by 6.
Therefore,
SA=1734mm^2
