Kendra has $ 7.35 in nickels and quarters. If she has 15 more quarters than nickels, how many of each coin does she have?
lozanna [386]

x*5 - quarter amount

(x+15)*25- nickels amount

(x*5)+((x+15)*25)=735

5x+25x+375=735

30x=735-375

30x=360

x=360/30=12 - number of nickels

x+15=12+15=27 - number of quarters

CHECK

12*5=60 ¢

27*25=675 ¢

675+60=735 ¢ or $7.35

State the factoring rule for difference of two squares a2-b2
ludmilkaskok [199]
<h3>Answer:  a^2 - b^2 = (a-b)(a+b)</h3>

The order of the factors does not matter.

So (a-b)(a+b) is the same as (a+b)(a-b)

This is known as the difference of squares factoring rule.

You can FOIL out (a-b)(a+b) and you'd get a^2+ab-ab-b^2. Note how the ab terms cancel leaving us with a^2-b^2. This confirms we have the correct factorization.
