Answer:

(x+7) / 3

Explanation:

Factorise the Top half to give :

x² + 12x+ 35 = (x+5)(x+7)

Factorise the bottom half to give :

3(x+5)

Cancel (x+5) from top and bottom to give :

(x+7) / 3

So our final answer is Option 3

Hope this helped and have a good day

(x^2+12x+35)/(3x+15)=(x^2+12x+35)/(3(x+5))=(x^2+5x+7x+35)/(3(x+5))=(x(x+5)+7(x+5))/(3(x+5))=\\=((x+5)(x+7))/(3(x+5))=(x+7)/(3)
