The complex number are formed by a real part and an imaginary part.
The imaginary part is indicated with the letter i.
2i is only imaginary, so it is not complex
i - 1 is complex but is out of the triangle.
1 - i indeed is complex and is inside the triangle
2 - 3i is complex but is out of the triangle.
So, the answer is 1 - i
It is seen in the figure given that there are three triangles with sides equal to a = 17 inches, b = 17 inches, and c = 20.5. Our angle c is the angle opposite side c and that is 74°. Using the equation given in the question,
A of triangle = ((17 in)(17 in)(sin 74°))(1/2)
= 138.9 in²
Then, we multiply this area by 3 since there are 3 triangles.
total area = (138.9 in²)(3) = 416.7 in²
The area of the figure is most approximately equal to 417 in².
The correct answer would be 2.1 miles, or answer B.

Answer:

Step-by-step explanation:

Distribute 2 through the parentheses

Add the like terms : 6x and 4x
Like terms are those which have the same base.

The negative integers are always but added but posses the negative ( - ) sign.
