So, x = 13, x = √3 and x =7i.
now, recall that for an EVEN radical, there are two possible roots, namely is say √3 is say hmmm some value "a", that means that a*a = √3, however, -a*-a is also √3, therefore, ±√3 are two valid values, and therefore -√3 is another one.
now.... keep in mind that, complex solutions or roots, never come all by their lonesome, their sister is always with them, the conjugate, so, for 7i or namely 0 + 7i, her sister is always around, 0 - 7i, which is the other root.
I believe that the answer is 20. I am not entirely sure though.
Answer: 
Step-by-step explanation:
Given: The sales of 10000 increased by 65% each year .
Let x be the number of years.
The rate of growth=65%= 0.65
The exponential growth function is given by

, where A is initial amount and r is the rate of growth in decimal.
Then the increase in the sales id given by :-

Answer:
sinB= 3/5, tanA=4/3, cosB=4/5
Step-by-step explanation:
You would multiply rows by seats to get the total so you multiply 24 by 18. so that would get you 432 seats in total. Hope it helps!
