Given that I no not see any explanation in the previos answer, I think you can benefit of this.

Exothermic refers only to the fact that the reaction releases energy in the form of heat when occurs. So, the enthalpy is higher at start and lower and the end.

Seen in this way, you can deduct that the change in enthalpy is negative, which is what the third option says.

The graph of y=x is shifted up 2 units and 3 units to the left. Which is the equation of the translated function?
krek1111 [17]

Check the picture below.

y = x\implies y = \stackrel{A}{1}(\stackrel{B}{1}x+\stackrel{C}{0})+\stackrel{D}{0} \\\\\\ \begin{cases} \stackrel{\textit{2 units up}}{D=+2}\\\\ \stackrel{\textit{3 units left}}{C=+3}\\ B=1 \end{cases}\qquad \implies y = \stackrel{A}{1}(\stackrel{B}{1}x\stackrel{C}{+3})\stackrel{D}{+2}\qquad \implies y=(x+3)+2

Jake walked all the way around the perimeter of a square playground that has sides n feet long, then he walked an additional 20
DENIUS [597]

Options :

Sarah, who walked a straight distance of n+10 feet.

Nancy, who walked around a square garden measuring n+5 feet on each side.

Jules, who walked around a rectangular room measuring n feet wide and 10 feet long.

Billy, who walked around a square lot measuring 20 feet on each side

Answer:

Nancy, who walked around a square garden measuring n+5 feet on each side.

Step-by-step explanation:

Given that:

Jake walked round the perimeter of a square with sides n feets long

Additional distance walked = 20 feets

Perimeter of a square = 4n

Where n = Length of the side

Hence Jake's total distance :

Perimeter walked + additional distance

4n + 20 feets

Comparing to Distance walked by Nancy:

Side length of square garden = n+5

Perimeter of the garden = 4 * side length

Perimeter of the garden = 4 * (n + 5)

Perimeter of the garden = 4n + 20 feets

Hence, Nancy walked the same distance as Jake
