In the Sahara Desert, one day the temperature was 58°C. On the same day, the temperature in Gobi Desert was -47°C. What is the difference between these two temperatures?

Our question is to find the difference between their temperatures on that particular day. Note that ⇨ difference is the keyword for subtraction. So, to find the difference we need to subtract their temperatures.

58°C - (- 47°C)

= 58°C + 47°C

= 105°C

So, there was a difference of about 105°C between the temperatures of the Sahara & the Gobi Desert on that particular day.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
