Answer:
wheres the question?
Step-by-step explanation:
Here are the answers for 10 and 12
Answer:
The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i )
Step-by-step explanation:
Given equation as :
3 x² + 6 x +15 = 0
The value of x fro the quadratic equation a x² + b x + c = 0 is obtained as
x =
So , from given eq , the value of x is now obtain as
x =
Or, x =
Or, x =
∴ x = ( - 1 + 2 i ) , ( - 1 - 2 i )
Hence The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i ) Answer
<span>1. Find the difference
2. Divide the difference by the original number it went up from.

450-375 = 75
75/375 = 0.2
You got a 20% raise.
Proof:
375*.2 = 75
375+75 = 450
