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.

Three consecutive even integers are such that the square of the third is 76 more than the square of the second. Find the three i
Arada [10]

Let n represent the interger l, the three consective intergers are represented by

n

n + 2

n + 4

The second one represent

(n + 2) {}^{2}  + 76 =(  n + 4) {}^{2}

Simplify both sides

n {}^{2}  + 4n + 4 + 76 =  {n}^{2}  + 8n + 16

{n}^{2}  + 4n + 4  =  {n}^{2}  + 8n - 60

4n + 4 = 8n - 60

4n + 64= 8n

64= 4n

n = 16

The intergers are 16,18,20
