The length of a rectangular room is 7 less than three times the width of the room. Which expression represents the room? A. 3w-4 B. 3w-7 C. (3w x 3w)-4w D. (3w x 3w)-7w

Option (B)

Step-by-step explanation:

Let the width of a rectangle= w

As per given information, length of a room is 7 less than three times the width of a room

3 times of a width of a room= 3 w

Hence Length of a room= 3 w- 7

We get the length of a room = 3 w- 7

And area= L ×B = w ( 3 w - 7)

Hence, Option (B) is correct answer

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,
