Answer:(-3 + 2i) × (2 + i)
Multiply this by using FOIL: First, Outside, Inside, Last.
Multiply the First numbers, -3 × 2.
Multiply the Outside numbers, -3 × i.
Multiply the Inside numbers, 2i × 2.
Multiply the Last numbers, 2i × i.
Use the distributive property to show FOIL: -3(2 + i) + 2i(2 + i).
Distribute the -3 to 2 + i and 2i to 2 + i.
Rewrite i² as -1.
-6 - 3i + 4i + 2(-1)
Now combine like terms, -6 - 2 and -3i + 4i.
-8 + i is your answer.

Answer:
the counting numbers and zero are whole numbers.
the counting numbers and their opposites, along with zero, are integers.
integers and decimal equivalents of fractions are rational numbers.
Answer:
The answer is 11/8 or 1 3/8
Step-by-step explanation:
First, you can break both fractions down into 3+1/4-1+7/8.
Second, use 3 subtract 1, you will get 2+1/4-7/8.
To subtract 7/8 you have to make both numbers denominator same.
1/4 will multiply by 2 on the top and the bottom.
After that, you will get 2 2/8-7/8.
2x8=16, 16+2=18
18/8-7/8=11/8 or 1 3/8
I know its gonna be confusing, but this is all I can do, sorry about that. :)
