Answer with Step-by-step explanation:

3/x²+14x+48 divided by 3/10x+60 is equal to

[tex]\dfrac{3/x^2+14x+48}{3/10x+60}[/tex]

=[tex]\dfrac{3\times (10x+60)}{3\times (x^2+14x+48)}[/tex]

=[tex]\dfrac{10x+60}{x^2+14x+48}[/tex]

=

[tex]\dfrac{10x+60}{x^2+6x+8x+48}\\ \\=\dfrac{10x+60}{x(x+6)+8(x+6)}\\ \\=\dfrac{10(x+6)}{(x+6)(x+8)}\\ \\=\dfrac{10}{x+8}[/tex]

Hence, Correct option is:

C- 10/(x+8)
