The temperature was -13°f and then rose 9°f. enter the addition expression that represents the final temperature.

-13 + 22 = 9

Step-by-step explanation:

This should be simple if I am not overthinking this

If the temperature started at -13 degrees F and rose to 9 degrees F

you just need to add 13 to 9 to find the "space" or difference betweent he numbers

When you do this you get 22

So its -13 + 22 = 9

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
