Arectangle has a height of 2x and a width of x^2+8x+15.
express the area of the entire rectangle.
your answer should be a polynomial in standard form.
area =

Step-by-step explanation:

we know that

The area of rectangle is equal to

where

b is the base of rectangle or width

h is the height of rectangle

we have

substitute the values

ddd

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
