Answer:
Sum of real parts: 12
Sum of imaginary parts: 3
Step-by-step explanation:
(22 − 5i) + (−10 + 8i)
Combine the real and imaginary parts in numbers 22 − 5i and −10 + 8i
22 − 10 + (−5 + 8)i
Add 22 to −10. Add −5 to 8
12 + 3i
So, the answer is:
Sum of real parts: 12
Sum of imaginary parts: 3i
The real part is 12, the imaginary part is 3
Order of operations so -6 × -5 = 30
-6 + 30 = 24 is the answer
Hope this helps!
Answer:
A
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
You can probably figure out the rectangle of 16 by 8 so no explaining there. 16×8=128. You know that diameter of the cirkel is equal to y so 8. The diameter of a cirkel is two times its radius. so 8=2r. r=4. The area of a cirkel is calculated by the formula \pi×r^2. Fill in r=4 in \pi×r^2 gives us \pi×4^2=16\pi. You only have half of the cirkel so 16\pi/2=8\pi. 128+8\pi=153.12 which is A.
