2100 + 809 equals to 2909.
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
Answer:
Step-by-step explanation:
250x^3-16
2(125x^3-8)
2[(5x)^3-(2)^3]
2(5x-3)[(5x)^2+5x*3+(2)^2]
2(5x-3)(25x^2+15x+4)
Answer:
The total weight change for the eight women was -24.
Step-by-step explanation:
In order to find the answer, you have to consider that average is calculated by dividing the total weight change by the number of women and you know that the average was they lost 3 pounds and there were 8 women:
Average= total weight change/number of women
-3=total weight change/8
total weight change=-3*8
total weight change=-24
According to this, the answer is that the total weight change for the eight women was -24.
