Equation
1/2(c-8) =
Distribute 1/2 through the parentheses.
1/2c - 4
Answer:
Nope, this is because the angles in a triangle add up to 180, whereas these values added are equal to 200 degrees

Answer:
B.He did not add the corresponding parts of the complex numbers.
Step-by-step explanation:
A mid point is a point that is of equal distance to two reference points.
Given: Find the midpoint of 5+(-3)i and 12+7i.
These expressions have two parts: the value and complex number parts.
Thus the addition ought to have been;
(5+(-3i)) + (12+7i) = (5 - 3i) + (12 + 7i)
= (5 + 12) + (-3i + 7i)
= 17 + 4i
The midpoint can be determined as:
Thus it can be observed that Raul did not add the corresponding parts of the complex numbers.
Just multiply 2 to every value inside the parentheses, the answer is 8x2 - 2x - 10
