Apainting is covering up some of the tiles on the wall. the tiled wall is shaped like a rectangle . there are 28 square tiles on the whole wall. how many of the tiles are covered by the painting?

The number of tiles are covered by the painting are 12.

Step-by-step explanation:

Consider the provided information.

The painting is covering up some of the tiles on the wall as shown below:

Here it is given that there are 28 squares tiles on the wall.

Total tiles = Number of tiles covered by the painting - uncovered tiles

28 =  Number of tiles covered by the painting - 16

Number of tiles covered by the painting = 28 - 16

Number of tiles covered by the painting = 12

Hence, the number of tiles are covered by the painting are 12.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
