NEED HELP ASAP WILL MARK AS BRIANLYEST In September, Ana did laundry 24 out of the 30 days in the month. Which value is equivalent to the fraction of days she did the laundry? 0.26 0.8 8% 38%

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

lol 2
