How do I do 123°15’-40°26’ ?

82° 49'

Step-by-step explanation: A degree is subdivided

into minutes and seconds.

1° = 60' and 1' = 60"

One degree = 60 minutes

123° 15' - 40° 26'

= 7395' - 2426'

= 4969'

= 82° 49'

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
