There are 5 letters
there are 5 possibilities for the first letter, and 4 possibilities for the second letter after the first letter is used up
so 5 * 4 = 20 possibilities
Step-by-step explanation:
the number which is a perfect cube :
125, because 125 = 5³
30% off 25: multiply 25 by .30 to find 30%: 7.5. Now subtract that from the sales price: 25-7.5=17.5
Do the same for store B: .40•30=12. 30-12=18.
So store A is better by $.50 :) hope this helps :)

question 4
y=2x^2-5x+9
y= 2x^2+5x-1

x=1
y= 2×1^2+5×1-1
y=6
