Photo-math take a picture of your problem and it will give you your answer
2x^2 + x + 3=0 has only complex roots.
The determinant is 1-4*2*3 = -23
-23 (or any determinant) is the part under the square root sign, If that determinant is negative, knowing you cannot take the square root of a negative number, we know the answers must be complex.
The perimeter is 1/2 the perimeter of ABCD because the scale factor is 1/2. It would be 10 units.
It’s D that is the answer
