Answer:
1. -19x
3. 23 - 8x
5. -18x + 2y
Step-by-step explanation:
first: 3x - x = 2x
2x - 22x = -20x
-20x + x = -19x
second one:
8 - (-15) = 23
12x - 20x = -8 x
23 - 8x
third:
-10x - 8x = -18x
3y - y = 2y
-18x + 2y
11 / 1/3
11 * 3/1
33/1
Fraction Form: 33/1
Simplified Form: 33
(2-7i)(9+5i)
18+10i-81i-35i^2
The answer is 35i^2 - 71i +18
