Hey, TailsIsTheBest!
Great question=)

Question:<span>What is the value of the expression f2 + 8 if f = 7?

Answer:22

Work:They already gave us the value of the variable f, so all we have to do it plug in 7 for f's place.

(7)2+8
7*2=14
14+8=22

I hope this helps;)
If you have any questions on my work, feel free to ask me.

If the values are placed right next to each other without a symbol, then you multiply them.
So, you multiply the value of 7 with 2, since they are placed right next to each other.
(7x2) + 8 = 14 + 8 = 22

Bill takes a total 60 minutes to arrive to school. Hence Bill's rate is equal to 14.4 km/60 minutes or 4 meters/ second.Amy's is 2 m/s faster than Bill's speed, then.
