Answer:
12/ x^2+7x
Step-by-step explanation: Took the test and got it right
The product of the expression 3/(x+7) and 4/x is equivalent to the expression 12/(x^2+7x) option 12/(x^2+7x) is correct.
Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
The polynomial can be represented as:
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
We have polynomial:
[tex]\rm = \frac{3}{x+7}\times \frac{4}{x}[/tex]
[tex]=\rm \frac{3\times4}{x(x+7)}[/tex]
[tex]\rm = \frac{12}{x^2+7x}[/tex]
Thus, the product of the expression 3/(x+7) and 4/x is equivalent to the expression 12/(x^2+7x) option 12/(x^2+7x) is correct.
