Answer:
Step-by-step explanation:
You first want to get rid of the numbers which are in parenthesis
(-345(-23)
This is a multiplication between negative numbers
The law of signs in mathematics states that negative times negative equals positive
(-) (-) = +
(-345(-23)= 7935
Then we multiply the number which is outside of the parenthesis (4x)
(4x)7935= 31740x
