Hey, TailsIsTheBest!
Great question=)

Question: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 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

Use the Pythagorean theorem. We have legs with lengths of 15 and 20 miles, now let's solve for the hypotenuse.

$a=15$
$b=20$
$c=?$

$a^2+b^2=c^2$
$15^2+20^2=c^2$
$c^2=400+225=625$
$c=25$

Your answer is 25 miles. Hope this helps! :)

Answer:

Any time you have a subtraction and a negitive right next to eachother, it means to add. So, you would add 13 and 1 to get 14, then keep the denominator 19 to get 14/19.
