That Equals = -60i. Hope im right :) Good luck
Answer:
Either x≈ -1.12 or x ≈0.45
Step-by-step explanation:
Using the quadratic formula to solve this, we will follow the steps below;
First, write down the quadratic formula;
x = -b ±√b² - 4ac /2a
From the question, the equation given is: 6x²+4x−3=0
comparing the equation given withe standard equation ax² + bx + c=0
a= 6 b= 4 and c = -3
We can now proceed to insert the values into the formula;
x = -4 ±√4² - 4(6)(-3) /2(6)
x = -4 ±√16+72 /12
x = -4 ±√88 /12
Either x = -4+√88 /12
x ≈0.45
OR
x = -4 -√88 /12
x≈ -1.12
Either x≈ -1.12 or x ≈0.45
Answer:
Step-by-step explanation:
Let the amount of the job is x.
You can do 1/2x in an hour.
Your friend can do 1/3x in an hour.
<u>Together you can do:</u>
- 1/2x + 1/3x = 5/6x of a job in an hour
<u>You need time to finish the job:</u>
- x ÷ 5/6x = 6/5 = 1.2 hours
