Jacksons rectangular bedroom has an area of 90 ft.². the area of his bedroom is nine times that of his rectangular closet. if the closet is 2 feet wide, what is its links?

The closet area is 1/9 of the bedroom area, so is (1/9)·(90 ft²) = 10 ft².

The width of the closet multiplied by the length is the area.

... length×(2 ft) = 10 ft²

... length = (10 ft²)/(2 ft) = 5 ft

The length of Jackson's closet is 5 ft.

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
