Answer:
x = 15
Step-by-step explanation:
We assume you want to find the value of x.
Know (or prove) that in this geometry, all of the right triangles are similar. That means the ratios of corresponding sides are proportional.
short side / hypotenuse = 9/x = x/25
x^2 = (9)(25) . . . . . . . . . . multiply by 25x ("cross multiply")
x = √((9)(25)) = (3)(5) . . . take the square root
x = 15

Answer: 81 people attended
Explanation:
Number of adults = 988 / 26 = 38
Number of students = 731 / 17 = 43
Total attendees: 38 + 43 = 81
Step-by-step explanation:
Any complex number is of the form: 
where a is real part and B is imaginary part.
Therefore, in given complex number: 
7 is real part.
is imaginary part.
Hence, first two options are correct.
Last two options are incorrect because of the following reasons:
is coefficient of 
& not 
Given number is a difference of a real number and imaginary number & not a sum of a real number and imaginary number.
