how do you find area of a rectangle?

Width x height

OpenStudy (jim766):

right..... also length times width so Length * width 16x^7 * 48x^4 do you know what to do next?

OpenStudy (anonymous):

add both answers together?

OpenStudy (jim766):

it is mult so you mult the coefficients the 16 nd 48 then you add the exponents to the like bases 7 and 4

OpenStudy (jim766):

16x^7 * 48x^4 768 x ^ 11
