If u = 3 – 4i and v = 3i + 6, what is u – v.?

Step-by-step explanation:

We have been given two equations and . We are asked to find the value of .

Let us subtract value of v from u as:

First of all, we remove parenthesis as:

Now, we will combine the real part of equation with real part and imaginary part with imaginary part as:

Therefore, the value of   is .

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
