You are building a dining room table for family dinners. The table has a length of 3x + 1 feet and a width of 3x - 1 feet. If the table has an area of 35 square feet, find the actual length and width.

Length 7 feet and Width 5 feet

Step-by-step explanation:

we know that

The area of the rectangle ( a dining room table) is equal to

where

substitute

Apply difference of squares right side

Remember that the length cannot be a negative number

so

x=2

Find the length

Find the width

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,
