Answer:

Sometimes

Step-by-step explanation:

When x is a nonzero integer, then x can be

  • negative;
  • positive.

If x is negative, then -3x is positive (multiplying negative number by -3 you get positive number).

If x is positive, then -3x is negative (multiplying positive number by -3 you get negative number).

So, the statement "When x is a nonzero integer, the quantity -3x will be negative" is sometimes true.

Find two consecutive even integers whose product is 288
Trava [24]
So I’m going to solve this using algebra OK?
So what you do is take the first integer as X.
Then we know that x(the first number) + X+2(the second number) is 288 right?
So we solve that saying x+x+2=288.
So 2X+2=288
2X+2-2=288-2 right?
So 2X=286.
So x is 286/2 right?
So x is 143.
Now the first number is 143 right?
So the second number should be 143+2 so 145.
I know they are not even but these are the solutions.
I don’t think there are any consecutive even numbers that add up to 288
