applying pythagoras's theorem.
Answer:
The correct complex numbers would be, -2 - 4i and 2 + 2i
(−2 − 4i) − (2 + 2i) = -4 - 6i
Step-by-step explanation:
(−2 − 4i) − (2 + 2i)
Subtract 2 + 2i from −2 − 4i by subtracting corresponding real and imaginary parts.
−2 − 2 + (−4 − 2)i
Subtract 2 from −2. Subtract 2 from −4.
-4 - 6i
So, the correct complex numbers would be, -2 - 4i and 2 + 2i
Answer:
43100 cubic feet
Step-by-step explanation:
Floor 1: 3700 * 8 = 29600
Floor 2: 50 * 30 * 9 = 13600
Total = 29600+13600=43100
3/8 because to find the area you multiply both numbers so 1*3 is 3 and 2*4 is 8 so your answer should be 3/8
