This is the concept of algebra, we are required to subtract the complex numbers. Thus;
(5-2i)-1(1+8i)
opening the brackets using the distributive property we get:
5-2i-1-8i
collecting the like terms we get:
5-1-2i-8i
=4-10i
the answer will therefore be:
4-10i
Answer:
13.9
Step-by-step explanation:
To get the length, or the hypotenuse, you do the equation a^2 + b^2 = c^2
Meaning you multiply those known lengths by themselves, then add them.
169 + 25 = 194
Then you find the square root of 194.
The square root would be 13.9283882772, or when rounded to the nearest tenth, 13.9
For the second one, what is the number before the x?
