Question

two consecutive negativee integers have a product of 30. what are the integers? separate the answers with a comma.

Answer 1

So if the numbers are consecutive, then that means one is just +1 of the other.

n is one of them.
n+1 will be the other one.

Now apparently their product is 30. So that just means multiply them together and you get 30 right?

n*(n+1)=30

So now you can solve for n with this equation.

Answer 2

ok

Answer 3

yep

Answer 4

would it be -6,5

Answer 5

Almost, but -6*5=-30 which is wrong.

See, when you solved for n that told you what possibilities you could have.

n=-6
OR
n=5.

But remember these aren't both your numbers. The next number is n+1 right? So add 1 to both answers and you get:

-6+1=-5

5+1=6

So now you see that:

(-6)*(-5)=30
6*5=30

However in the question they said they wanted the consecutive negative integers, not the positive ones. So your answer is:

-6 and -5.

Answer 6

ok

Answer 7

the length and width of a rectangle are consecutive even integers. the area of the rectangle is 120 square units. what are the lenght and width of the rectangle

Answer 8

would that be 10 ,12

Answer 9
