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.
