Can a math wiz solve this problem please?? quick!?

Question

What are 5 integers whose product is less than zero and whose sum is -18? the first to get it right gets 10 points!!

Answer 1

all negative 6, 5, 4, 2, 1,

Answer 2

Since (-x * -y) = +xy and (-a * -b) = +ab and -z = -z

-x * -y * -a * -b * -z = xy * ab * -z

Any 5 negative intergers which add up to be -18, will give you a value less than 0

-1 + -2 + -3 + -4 + -8 = -18
-1 * -2 * -3 * -4 * -8 = -192

-1 + -2 + -3 + -5 + -7 = -18
-1 * -2 * -3 * -5 * -7 = -210

There are others

Answer 3

I'll tell u
choose any 4 positive integers: a, b, c, and d
choose the 5th integer, x such that :
1- it's a negative integer
2- |x| > (a+b+c+d), so that x-(a+b+c+d) = negative value
3- |x| - (a+b+c+d) = 18
so x - (a+b+c+d) = -18
and as all we know negative*positive = negative,
positive *positive =positive
so x which is -ve, when multiplied by (a*b*c*d) which is +ve
the result will be -ve, i.e < zero
ao u have an infinite number of solutions
have a nice day

Answer 4

There are many possible answers, but here's one:

2 3 -5 -8 -10

Answer 5

-100+50+35-3+1= -18

Answer 6

The answer is -5,-2,-16,2,3.Product is -960 and sum is -18

Answer 7

There are way too many combinations.
You can select any 3 integers first, and still have inifite number of answers. For example, choose the first 3 number as 1,2,3
You can have
1,2,3,-25,1
1,2,3,-26,2
1,2,3,-27,3
1,2,3,-28,4
...
If the first 3 are chosen as 2,3,4, then you could have
2,3,4,-28,1
2,3,4,-29,2
2,3,4,-30,3
2,3,4,-31,4
...

Answer 8

-18=-9 +7 -10 +2 -8
(-9)*(7)*(-10)*(2)*(-8)=-10,080
