Area = length x width
area = 2 3/4 x 2/5
area = 1 1/10 feet :)
A table will generally give you an output value for each of several input values. To find the average rate of change over some range of inputs, divide the difference between output values by the difference between input values for the corresponding inputs.
For example, consider the table
input .... output
.. 1 ............ 3
.. 3 ........... -5
The average rate of change between these input values is
... (change in output)/(change in input) = (-5 -3)/(3 - 1) = -8/2 = -4.
Ok, so we know that the product of means something added, and we are given that eleven and a number are less than 53. So the equation is 11+X<53.
