Answer:
Step-by-step explanation:
1. Factor out the imaginary number "i" from the trinomial. This leaves you with:
x^2 + x + 1 = 0
2. From here you need to complete the square and solve for x, which should give you the above answer once simplified.
3. If you wanted to check the answer you can plug it back into the equation to see if you get 0.
Answer:113
Step-by-step explanation:
Answer:
3/50
Step-by-step explanation:
It's not as hard as you might think! You can just multiply the denominator and numerators separately. So in this case, you just need to do 9*1 and 25*6. This means that the answer is just 9/150, simplify it and you get, 3/50!
Answer: 2 6/15 < 2 4/9 < 2 3/5 < 2 2/3
Step-by-step explanation:
Each bag of popcorn costs $2. 5
You can solve it by creating an equation. This one can be:
40 -12x = 10
Undo the operation.
40 -12x = 10
-40 -12x = 10 -40
Eliminate the 40. This will live you with the following.
-12x = -30
Divide -12x by -12. Do the same with the -30
-12x = -30/ -12
This will give you the answer.
x = 2.5
