Step-by-step explanation:
The answer to 9a is that A and B have to be on the right side of the number line but A has to be greater than B.
The first and second box for 9c is > .
The complex solutions come in pairs and the only difference between them is the sign between the real and imaginary part, so one of the other two solutions is
![2+3i](https://tex.z-dn.net/?f=2%2B3i)
. The third solution can be easily found using the rational root theorem, and it's equal to -1.

The new triangle is gonna be bigger. But how big? Let’s look at A.
A= 2,8
Look at A’, it’s 6,24. See a pattern??
Multiply 2,8 by 3. It’s triple the amount, therefore the scale factor is 3.
To double check, multiply by 3 to B and C and see what you get.
