Answer:
4
Step-by-step explanation:
To simplify
[tex]\frac{4}{x+3}[/tex] ÷ [tex]\frac{1}{x+3}[/tex]
Change division to multiplication and turn the second fraction upside down, that is
[tex]\frac{4}{x+3}[/tex] × [tex]\frac{x+3}{1}[/tex]
Cancel the factor (x + 3) on the numerator/ denominator , leaving
[tex]\frac{4}{1}[/tex] = 4
Answer:
The answer is 4, because the (x+3) cancels out.
Step-by-step explanation:
4/(x+3) / (1/x+3) =
The numerator will be multiplied by the inverse of the denominator:
4/(x+3) * (x+3)/1 =
Cross out the (x+3) in the numerator and the denominator.
What remains is:
4 / 1 = 4
