Answer:
8 + 4i
Step-by-step explanation:
Put corresponding terms above each other and subtract in the usual way.
z = 3 + 5i
<u> w = -5 + i
</u>
z - w = 8 + 4i: 3 - (-5} = 8; 5i - 1i = 4
i
I think the answer is as follows:
70/574 = x/100
574x=7000
574/7000 = .082
final answer is 820
820 x 70% = 574
<span>t in (-oo:+oo)
(3*t)/2+7 = 4*t-3 // - 4*t-3
(3*t)/2-(4*t)+3+7 = 0
(3*t)/2-4*t+3+7 = 0
10-5/2*t = 0 // - 10
-5/2*t = -10 // : -5/2
t = -10/(-5/2)
t = 4
t = 4 is the answer
hope it helps~

Your answer is option D. √(15² + 19²). This is because the line PQ is the hypotenuse of this right triangle, so you can use the formula a² + b² = c² to find its length, which means it would equal the square root of 15² + 19², which is what option D expresses.
I hope this helps!
