Express the area of the rectangle in term of x
aalyn [17]

Answer:

Area = 12-\frac{4}{35}x

Step-by-step explanation:

Length of the given rectangle 'l' = (15 - \frac{1}{7}x)

Width of the given rectangle 'w' = \frac{4}{5}

Area of the rectangle = lw

                                    = \frac{4}{5}(15-\frac{1}{7}x)

                                    = \frac{4\times 15}{5}-\frac{4}{5}\times \frac{1}{7}x

                                    = 12-\frac{4}{35}x

Therefore, expression that defines the area of the given rectangle will be,

Area = 12-\frac{4}{35}x
