Answer:
It seems like you're demonstrating the Distributive Property in the given equations.
For the equation
8(−5+7)=8(−5)+8(7):
Evaluate the left side:
8(−5+7)=8(2)=16
Evaluate the right side:
8(−5)+8(7)=−40+56=16
So, the equation is true, confirming the Distributive Property.
8(−5)=, it's equal to −40.
