Follow PEMDAS. First is multiplication.
Follow the FOIL method: (First, Outside, Inside, Last)
<span>(8 - 3i) - (8 - 3i)(8 + 8i)
</span>8(8) = 64
8(8i) = 64i
-3i(8) = -24i
-3i(8i) = 24 (note: two "i"'s = -1)
Combine like terms
64 + 64i - 24i + 24
64 + 40i + 24
88 + 40i
Now subtract 88 + 40i from 8 - 3i
(8 - 3i) - (88 + 40i) = -80 - 43i (Note: the signs in the parenthesis change, because you are subtracting as a whole)
-80 - 43i is your answer
hope this helps
Answer:
if you're talking about renaming it in word form it would be a six hundred- thousand or is you're doing it in an equation its gonna be (6x10) x (10x1000)
Step-by-step explanation:
Complete question is;
Jane is training for a triathlon. After swimming a few laps, she leaves the health club and bikes 16 miles south. She then runs 12 miles west. Her trainer bikes from the health club to meet jane at the end of her run. Use the pythagorean theorem to write an equation for the distance janes trainer bikes
Answer:
x = √(12² + 16²)
Step-by-step explanation:
We are told that;
She bikes from health club to South = 16 miles
From South to West = 12 miles
Her trainer bikes from the health club to meet her at the end which is west.
I have attached a diagram showing this movement in form of a triangle.
From the diagram I attached, I have depicted the distance the trainer bikes as x.
Using pythagoras theorem;
x² = 12² + 16²
x = √(12² + 16²)
The answer is probably C.
