Answer:
The square root of -100 is 10i.
Step-by-step explanation:
The temperature in London at 2pm is 14°C
Well first turn 1/7 and 1/5 into decimals which would be .142857 and .2 Add those to 7 and 5 to get 7.143 (I rounded this to the nearest thousandth) and 5.2 Divide those and you get 1.374
The length is 7 with a width of 5, so the area is 35
(-4)^-3 =
-4^-3 = 
Basically in this situation there is no difference whether parenthesis are used or not.
