Answer:
-4, -4, 3, 8, 8
Step-by-step explanation:
-4(5+(-2))=-4(5)+-4(-2)
This is because of the distributive property. You have to distribute the 4 to the 5 and the -2.
-4(3)=-20+8
This is because since both the 5 and the -2 are being multiplied by -4, you can combine the 5 and the -2 to get 3 and then multiply that by -4.
This means (-4)(-2)=8
This is because (4)(2)=8 and two negatives make a positive.

When you multiply terms with like bases you add the exponents together. The base stays the same. When you divide terms with like bases you subtract the exponent of the denominator from the exponent of the numerator. This is called getting the power of a power.
