Answer: C: (x+6)(x-2); 84 square feet.

Step-by-step explanation:

it says that the length of hallway is 6 feet longer than 8 feet i.e 14 feet and width is 2 feet shorter that 8 feet i.e 6 feet.

so the the area will be $(x+6)(x-2)$

so the area of hallway be 14 x 6 i.e 84

and the area of square 8 x 8 i.e 64

45 ÷ 3 = 15
21 ÷ 3 = 7
12 ÷ 3 = 4

(4 + 15) x 7 = 133

OR if you’re using bedmas/pedmas

4 + (15 x 7) = 109

Answer:

a ≈ 5.3

Step-by-step explanation:

Using Pythagoras' theorem

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

a² + 6² = 8², that is

a² + 36 = 64 ( subtract 36 from both sides )

a² = 28 ( take the square root of both sides )

a = $\sqrt{28}$ ≈ 5.3 ( to the nearest tenth )
