ANSWER
![-48-25i](https://tex.z-dn.net/?f=-48-25i)
EXPLANATION
We want to simplify the expression,
![(-19+7i) - (29+32i)](https://tex.z-dn.net/?f=%28-19%2B7i%29%20-%20%2829%2B32i%29)
Let us expand the bracket to obtain,
![-19+7i-29-32i](https://tex.z-dn.net/?f=-19%2B7i-29-32i)
We now group the complex number parts and real number parts.
![-19 -29+7i-32i](https://tex.z-dn.net/?f=-19%20-29%2B7i-32i)
We simplify further to obtain,
![- 48-25i](https://tex.z-dn.net/?f=-%2048-25i)
This is in the form,
![a+bi](https://tex.z-dn.net/?f=a%2Bbi)
where
![a=-48](https://tex.z-dn.net/?f=a%3D-48)
and
Answer:
A
Step-by-step explanation:
To sovle this we must combine the numbers togther and the variables togther.
We have:
8c+6-3c-2
Lets take out the c's and combine them:
8c -3c
=
5c
Now lets take out the numbers:
6-2
=
4
Now lets put these back together and we get the expression:
5c+4
This looks like A.
Hope this helps! :D

Answer:
Add 6 each time.
Step-by-step explanation:
Figure 1 has 4 tiles.
To go from figure 1 (4 tiles) to figure 2 (10 tiles), you added 6 tiles.
To go from figure 2 (10 tiles) to figure 3 (16 tiles), you added 6 tiles.
∴ the rule is to add 6 tiles each time.
