Answer:
Step-by-step explanation:
x +3 I x⁴ + 0x³ - 6x² + 0x -28 I x³ - 3x² + 3x - 9
x⁴ + 3x³
<u>- - </u>
-3x³ - 6x²
-3x³ - 9x²
<u> + + </u>
3x² + 0x
3x² + 9x
<u> - - </u>
-9x -28
-9x - 27
<u> + + </u>
-1
P(x) =(x +3)* (x³ - 3x² + 3x - 9) + (-1)
If you would like to solve for the positive value of x, you can do this using the following steps:
6 * x^2 - 54 = 0 /6
x^2 - 9 = 0
(x - 3) * (x + 3) = 0
1. x = 3
2. x = - 3
The correct result would be x = 3.
Answer:
it is 42 degrees
Step-by-step explanation:
the angle x is the same as the parallel angle
(Observed data - Accepted standard) divided by the accepted standard. Then all of that is multiplied by 100.
( ( O - A ) / A) * 100
