If you start from a temperature of -6° C and you need to lower that temperature of 20 more degrees, you have to subtract:

So, the temperature in Antarctica is -26° C

Answer:
length = 24, width = 9
Step-by-step explanation:
Let's call the length and width of the first rectangle w + 15 and w respectively. This means that the length and width of the second rectangle is (w + 15) - 2 and w + 5 respectively. Since the perimeter of the second rectangle is 72, we can write:
2 * ((w + 15) - 2 + w + 5) = 72 because perimeter = 2 * (length + width)
(w + 15) - 2 + w + 5 = 36 (Divide by 2)
2w + 18 = 36 (Combine like terms)
2w = 18 (Subtract 18)
w = 9 (Divide by 2)
This means that the length and width are 24 and 9.
