Answer:
140
Step-by-step explanation:
5 times 4 is 20 which is the amount of browiners 20 times 7 is 140
It seems you tried to write √(-20)
use the fact tha -1 = i^2
Then, √(-20) = √(20i^2) =(√20) i = (√(5*4))i = 2√5 i = 2i√5, which seems to be what you tried to write in the option B.

Answer:
3x + 2 = 50
16
Step-by-step explanation:
According to the given situation, the equation to determine the number of friends is shown below:-
We assume the number of friends is x
50 - 3x = 2
-3x = -48
3x = 48
x = 16
So, the equation is
3x + 2 = 50
and the number of friends is 16
Therefore, the equation to determine the number of friends we just solved the above equation.
