the answer would be A.

7x × X gives you 7x^2

7x × 2 gives you 14 X

so the answer is the square root of 7x^2 + 14 X

Answer:

correct option is A) [tex]\sqrt{7x^{2}+14x}[/tex]

Step-by-step explanation:

provided expression is [tex]\sqrt{7x} \times\sqrt{x+2}[/tex]

since, [tex]\sqrt{m}\times\sqrt{n}=\sqrt{mn}[/tex]

[tex]\sqrt{7x}\times\sqrt{x+2}[/tex]

[tex]\sqrt{(7x)\times(x)+(7x)\times2}[/tex]

[tex]\sqrt{7x^{2}+14x}[/tex]

Which means correct option is A) [tex]\sqrt{7x^{2}+14x}[/tex]
