Answer: hi i am not sure what questions you need but look below.
1. D. The temperature dropped 4 degrees each hour for 5 consecutive days.
2. Brenda simplified the expression correctly.
Explanation:
1. the equation is -4(5)=-20.
- means that the number is decreasing or below zero. so If the temp. dropped 4 degrees each hour for 5 days then the expression for that would be -4(5)=-20
2. Brenda is correct because -5x+(2+x)= -5+x+2
You must break the expression up. -5x +x and -5x + 2. Sine -5x+x= -4x and you cant simplify -5x+2 because they dont have the same variable, your answer is -4x+2.
You are welcome
