The scale factor is 5
In the first image, you can see that the pre image square it 1 unit long and the image is 5. How do you get 1 to 5, you multiply by 5. So the scale factor is 5.
Alright so, let’s break this down.
To find the first coordinate you need to solve the first equation
To do that you can do
6+9=15
So that mean 3x has to be equal to 15
You divide 15 by 3
The answer to that is the solution to the first equation, or the first coordinate.
For the second one, you know x has to be negative because the solution is negative
2x is going to have to equal -20
-20/2 gets you the solution
Remember that it will be negative
You now have both of the coordinates
You take coordinate A and technically add coordinate B to it
You do that because B is negative and A is positive
Then you have the answer to c
Given:
To find:
The product of the expression.
Solution:
Take out -4 as a common factor in Last two terms.
Make sure the terms in both brackets must be same.
Take out common factor (2y - 5) from both terms.
4 can be written as 2².
Using the identity: 
.
The product is 
.
