Answer:
A. x²/y³
Step-by-step explanation:
Given the following data;
Length = x³y⁴
Width =
Ratio = length/width
Simplifying the equation by applying the law of indices (division), we have;
Hence, rearranging the above values;

<em>Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³. </em>
Answer:
f(19)=3/21-4=-3.857
Step-by-step explanation:
f(x)=3/(x+2)-sqrt(x-3)
f(19)=3/(19+2)-sqrt(19-3)
f(19)=3/21-sqrt(16)
f(19)=3/21-4
f(19)=-3.857
