The temperature went from 14°f to -17°f. which of the following expressions could be used to find how much the
temperature changed?
14- (-17)
-17 + 14
-17 - 14
14+ (-17)

31 decrease in temperature.

Step-by-step explanation:

We are subtracting -17 from 14 .

Temperature change = 14 - (-17)

= 14 + 17

= 31 degrees decrease in temperature.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
