Answer:
14 +2i
Step-by-step explanation:
For this sort of problem, you can treat i as though it were a variable. Combine like terms.
(8 -7i) +(6 +9i) = (8 +6) +(-7 +9)i
= 14 +2i
Answer:
r = 2.55
Step-by-step explanation:
The formula for finding the radius of a circle using the area is r = √A/π
with the r being the radius. the A being the area, and the π being pi (we'll use 3.14).
So the equation should look like this:
r = √(20.4/3.14)
Find the quotient of 20.4/3.14 and round to the nearest tenth
r = √6.5
Find the square root and round to the nearest hundredth
r = 2.55

Answer:
result is $6432.00 | 221.43

Lets expand both multiplications first.

Simplify down the right side.

Add 38.25 to both sides.

Subtract 11.22x from both sides.

Divide by -21.42 on both sides. Because we're dividing by a negative, we need to change the inequality direction.

This means, out of the options available, (-2.5, ∞) is the correct answer.
