a rectangle has a length of x3y4 inches and a width of xy7 inches . Which expression represents the ratio of the length of the r
Oxana [17]

Answer:

A. x²/y³

Step-by-step explanation:

Given the following data;

Length = x³y⁴

Width = xy^{7}

Ratio = length/width

Ratio = \frac{x^{3}y^{4}}{xy{^7}}

Simplifying the equation by applying the law of indices (division), we have;

\frac{x^{3}}{x} = x^{3} - x^{1} = x^{3-1} = x^{2}

\frac{y^{4}}{y^{7}} = y^{4} - y^{7} = y^{4-7} = y^{-3}

Hence, rearranging the above values;

Ratio = \frac{x^{2}}{y^{3}}

<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>
