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

hram777 [196]
The area of the triangle is 
a=( m x n) /2  in cm² , implies   2xa = m xn
the area of the rectanglle
A= n x m  in cm²
but we know  <span>  2xa = m xn = A,  </span>
that means  the surface of the rectangle is 2 times of the area of the triangle
