15: (x+y+z)/3 = 6 so, x+y+z = 18.Range = highest number - lowest number. For the max range, at least 1 of the numbers must be 1. 1,1,16. 16-1 = 15

Quadractics factorise into double brackets like (x-a)(x-b). We ave to find the facors of -21 which add to make +4. 7 and -3 suffice. (x-3)(x+7) Then x will be equal to 3 and -7 for the equation.

Genes in DNA encode protein molecules. The first step of expressing a gene is transferring the information in DNA to a messenger RNA (mRNA) molecule, by a process called transcription. DNA Helicase unwind...
