im going give 60 point please answer The temperature inside the command center is 21 degrees C. The temperature outside the command center is -12 degrees C. What is the difference in temperature

33 degrees

Step-by-step explanation:

It is 21 degrees inside the command center and negative 12 degrees outside.

You want to find the difference between these, which means you want to subtract.

That will look like:

21 - (-12) = ?

since you have two negative signs next to each other, they will cancel each other out.

Our new equation:

21 + 12 =

21 + 12 = 33

The difference between these two temperatures is 33 degrees.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
