If one solution is -3-5i then the other solution will be -3+5i
So, Option A is correct.
Step-by-step explanation:
We need to find the other solution of the quadratic function, when one solution is -3-5i
The quadratic equation is of the form: 
The complex roots of the quadratic equation are of form: 
So, if one solution is -3-5i then the other solution will be -3+5i
So, Option A is correct.

Answer:
9
Step-by-step explanation:
Less means minus, so basically X ( something ) - 9 is 0
X - 9 = 0
You add 9 on each side
X = 0 + 9
X = 9
Basically, all you're doing is the reverse, you start with 0 and do the opposite of taking away 9 which is adding nine so that you get the number:
0 + 9 = 9
Hence the number is 9

Answer:
142.5, rounded to 143 women.
Step-by-step explanation:
A squadron with 750 members is the common multiple of the sum of 19 and 81.
Therefore, the number of women in a squadron is equal to [750 : (19 + 81)] x 19 = 142.5.
