Leora wants to paint the nursery on her house. the nursery is an 8-by-13-foot rectangle, and the ceiling is 9 feet tall. there is a 3-by-6.5-foot door on one wall, a 3-by-6.5 foot closet door on another wall, and one 2-by 1.5-foot window on the third wall. the fourth wall has no doors or windows. if she will only paint the four walls and not the ceiling or doors, how many square feet will she need to paint

336 ft²

Step-by-step explanation:

The rectangle is   13  ft long  and  8 width  that means we have  two walls 8* 9   and  two walls  13*9

Total walls area is

2*8*9 + 2*13*9   =   144  + 234   =  378 ft²

then we subtrac  , areas of door, closet and windows

3 * 6.5  =  19,5 ft²

3 * 6,5  =  19,5 ft²

2 * 1,5   =   3   ft²

               42 ft²

Then area to paint    378  -  42   =  336 ft²

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
