Answer:
15+2i
Step-by-step explanation:
Hi there!
We are given the following expression:
(7-4i) + (8+6i)
And we want to write it as a complex number in standard form
Standard form is <u>a+bi</u>, where a is the real part of the number and bi is the imaginary part of the number.
We can open up the parentheses on the expression
7-4i+8+6i
Now combine the like terms (add 8 and 7 together, then add -4i and 6i together)
<u>15+2i </u>
The complex number is now in standard form
Hope this helps!

Answer:
51 notes
Step-by-step explanation:
Firstly we need to get the value of the 200 pounds in koruna
From the question, 1 pound is 25.82
200 pounds will be;
200 * 25.82
= 5,164 koruna
So to know the number of possible 100 koruna bills, we simply need to divide what we have by 100
We have this as :
5,164/100
= 51.64
So the number of notes she would be is 51 100 koruna notes
X = 8 since the two triangles are congruent, measure of angle J is the same of the measure of angle T ..therefore you can set up: 97+37+4x+14 = 180..(total degrees in a triangle). now solve for x
