Answer:
5-46i
Step-by-step explanation:
first multiply your (10-4i)(4-5i) so that would be 20-66i when simplified. then add that to -15+20i so it would look like 20-66i+(-15+20i). then simplify and you should get 5-46i.
10°C
The temperature is 50°F
Let's assume that 50°F = x°C
The formula is;
(x°C × ) + 32 = 50°F
x°C = 50 - 32 = 18
x°C = 18
x°C = × 18 = 10°C
So 50°F is equal to 10°C.
-18
