Answer:
+ or - square root of 5, and + or - i
Step-by-step explanation:
(x^2 + 5)(x^2 + 1)= 0
Set each set of parentheses equal to zero:
x^2 + 5 = 0; x^2 = -5, so x will equal plus or minus i times the square root of 5.
X^2 +1 = 0; x^2 = -1, so x will equal plus or minus i times the square root of one, which is just i
If you are looking for the median number, it would be the number in the middle which is 50

Answer:
B. <em>x + 0.2x</em>
Step-by-step explanation:
0.2 is equal to 20%
x represents the amount of dollars, and 20% of <em>x </em>would be written as 0.2x.
The 20% of x would be added to the money before the 20%, so, the answer is b, <em>x + 0.2x</em>.
