Express The Area Of The Rectangle In Term Of X class=

Sagot :

Answer:

Area = [tex]12-\frac{4}{35}x[/tex]

Step-by-step explanation:

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

Width of the given rectangle 'w' = [tex]\frac{4}{5}[/tex]

Area of the rectangle = lw

                                    = [tex]\frac{4}{5}(15-\frac{1}{7}x)[/tex]

                                    = [tex]\frac{4\times 15}{5}-\frac{4}{5}\times \frac{1}{7}x[/tex]

                                    = [tex]12-\frac{4}{35}x[/tex]

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

Area = [tex]12-\frac{4}{35}x[/tex]
