When Erik went to bed one winter night in northern Minnesota, the temperature was -2°F. By the time he got up the next morning, the temperature had dropped to -17°F. Assuming the temperature dropped steadily through the night, what was the temperature in the middle of the night? A. -8.5°F
B. -15°F
C. -9.5°F
D. -19°F

-9.5 f

Step-by-step explanation: The temperature needed to drop steadily through the night so find the difference between -2 and -17 and you'll get 15.  The temperature dropped by 15 degrees total and half of 15 is 7.5.  Halfway through the night the temperature was -7.5-2 degrees or -9.5f.

2 is the final ! : )

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
