Answer: 8
Step-by-step explanation:
1. Rewrite the equation:
-2x^3 - 3x^2 + 4 x = -2
2. Plug in the value of x, -2
-2(-2)^3 - 3(-2)^2 + 4
3. Use order of operations (PEMDAS):
-2(-8) - 3(4) + 4
= 16 - 12 + 4
= 8
Answer:
Step-by-step explanation:
If you want to factor this, you have to use the quadratic formula to do so.
For us, it looks like this:
which simplifies to
Since it breaks every mathematical rule to have a negative number under an even index radical, we have to deal with that using the imaginary "i". You should know at this point that
so we will do a rewrite on that equation above:
which simplifies further to
This is the answer but we can separate it into its proper standard form which is
and
According to my calculations it should be 77
6:45pm. because from 4 to 12 would be 4 hours then subtract 5 more hours leaves you at 7:25 pm. now subtract 45 from that which leaves you at 6:45 pm.
