F ( x ) = x^4 + 16 x² =
= x² · ( x² + 16 )
For x² + 16:
x 1/2 = (0+/-√(-64))/2= +/-8 i /2 = +/- 4 i
x² + 16 = ( x + 4 i ) · ( x - 4 i )
Answer:
f ( x ) = x² · ( x + 4 i ) · ( x - 4 i )
A= x+z .... -x from each side and you gots a-x=z
Answer:
10,000
Step-by-step explanation:
using PEMDAS we multiply the exponent first to get 5*20*100, now they are all multiplicative so we go left to right, 100*100 which is 10,000
Answer: $18
Step-by-step explanation:
60% of original cost means 40% is taken off
40% = 0.4
30 x 0.4 = 12 so that is how much will be taken off
30-12= 18
$18
7. 22 / 3 = 7.3333 . basically just rounded it
