If 3 times a square of an integer is added to 1 times the integer, the result is 2
jarptica [38.1K]
Let unknown integer be n.

So then your sentence would translate to 3n² + n = 2.

If you need to solve for n then we can move 2 to left side by subtract both sides by 2:

3n² + n - 2 = 0

Now you can factor:

3n² + 3n -2n - 2 = 0

3n( n + 1 ) - 2( n + 1 ) = 0

( 3n - 2 )( n + 1 ) = 0

3n - 2 = 0   OR   n + 1 = 0

3n = 2   OR   n = -1

n = 2/3   OR   n = -1


Final answer: n = 2/3   OR   n = -1

Ymorist [56]

Answer:

20

Step-by-step explanation:

Multiples of 10 are: 10, 20, 30, 40, 50, ... and so on.

Only one of them: 20 falls between 15 and 28.

Other conditions are also true for 20 - it has a factor that is an even number (all its even factors are: 2, 4, 10, 20) and it has a factor that is an odd number (all its odd factors are: 1, 5).
