Answer:
1/2
Step-by-step explanation:
1/4(1−2/3)2+1/3
1/4(1 /3)2+1/3
1/12*2+1/3
1/6 + 1/3
1/6 + 2/6
3/6
1/2
Four consecutive integers... n, n+1, n+2, n+3.
The product of the 1st and 4th is four less than twice the 1st multiplied by the 4th.
n(n+3)=2n(n+3)-4 perform indicated multiplications...
n^2+3n=2n^2+6n-4 subtract n^2 from both sides
3n=n^2+6n-4 subtract 3n from both sides
n^2+3n-4=0 factor
n^2-n+4n-4=0
n(n-1)+4(n-1)=0
(n+4)(n-1)=0, and since n>0
n=1
So the four numbers are 1, 2, 3, 4
check...
1(4)=2(1)4-4
4=8-4
4=4
6 x 500 = 6 x _5_ hundreds... [5 is the answer]
