Answer:
A
Step-by-step explanation:
The easiest way to figure this out is to substitute in the variables. So for a, 2=-5+7 is correct, and 7=0+7 is correct as well. If you were to look at the other answers, you would see that the equation would not match up. Hope this helps!
The answer is -9 + 9i. Hope this helped.
we are given

Since, we have to solve for w
so, we will isolate w on anyone side
Multiply both sides by 5



so,
option-D..........Answer
Uh.... She would have no money.
42 + (-65) = ?
= -23
Did you write the problem wrong?
The straight lines are asking to find the modulus or the size of the complex number.
For a complex number z = x + iy, [z] = √(x^2 +y^2)
Where x = Real Number, y = Imaginary number.
For 3 +i, x = 3, y = 1 (Note y is what number that is attached to i)
[3 + i] = √(3^2 +1^2) = √10 = 3.162
