Show all work. A gardener wants to create a rectangular garden with length of 8x - 4y ft. and width of 5x + 9y ft. What is an algebraic expression for the area of the garden? Be sure to multiply this out, express in simplest correct mathematical form, and include units.

A = lw A = (8x-4y)(5x+9y)

SO LENGHT TIME WIDTH 40X-36Y

OpenStudy (anonymous):

no

OpenStudy (anonymous):

it multiplies out to 40x^2 + 72xy - 20xy - 36y^2

OpenStudy (anonymous):

which simplifies to 40x^2 + 52xy - 36y^2

OpenStudy (anonymous):

OH OK THANKS

you can simplify that more
