there are 26 possible letters to choose from and there are 3 letters
there are 10 possible numbers to choose from and there are 3 numbers
combinations = 26 x 26 x 26 x 10 x 10 x 10 = 17,576,000
Y=-4+3x is different because all others have a negative 4 AND a -3x
Answer:
I think that Rule: xn = n2
Answer:
15 days. 5 divided by 1/3 is 15
Area = 304 cm^2
perimeter = 70
perimeter = 2(l+w)
70 = 2(l+w)
70/2 = l+w
35 = l+w
Now suppose the length would be = x
width would be= 35-x
NOW Area = l*w
304 = x * (35-x)
304 = 35x -x^2
x^2-35x+304 = 0
use quadratic formula to solve next ok
