Answer:
Step-by-step explanation:
Use the distributive property to get rid of the brackets.
9i + 2*7 + 2*3i Use the multiplication property to simplify the imaginary terms
9i + 2*3i + 2*7 Do the same to the real term
9i + 6i + 14 Use the addition of like terms property
15i + 14 And that's your answer.
You may not like my terminology, but you have to remember that every text teaches this differently.

Answer:
yes. -40°C = -40°F
Step-by-step explanation:
The relationship between the two temperature scales is ...
C = 5/9(F -32)
If we set the numerical values equal, we have ...
F = C
F = 5/9(F -32) . . . . .substitute for C
9F = 5(F -32) . . . . . multiply by 9
4F = -160 . . . . . . . . eliminate parentheses, subtract 5F
F = -40
The two temperature scales have the same value at -40°.

That's the bottom mark on the thermometer scales attached. (Unfortunately, those scales seem to be slightly misaligned. 0°C doesn't line up exactly with 32°F, either. Oops.)
