Answer:
m= 0
Step-by-step explanation:
this is the right answer
-7-14m+49=42+7m
42-14m=42+7m
14m+7m=42-42
21m=0
m=0
Answer:
The answer will be listed below.
Step-by-step explanation:
First of all, you want x to by itself, so distribute the three to both x and negative 4 so you'll get 3x-12=2x+6.
Now, subtract 2x from both sides and add 12 to both sides and you'll get an answer of x=19. From that, you are able conclude that this equation has one solution.
I should say 5 is the most clearest answer to me
Answer:
See below ~
Step-by-step explanation:
<u>Q1</u>
- y = (x + 3i)(x - 7)
- y = x² + 3ix - 7x - 21
- <u>y = x² + (3i - 7)x - 21</u>
<u>Q2</u>
- y = (x - √5)(x - i)
- y = x² - √5x - ix + √5i
- <u>y = x² - (√5 + i)x + √5i</u>
