Help please! Answer asap! I need smart people to help me!! Question is on photo!

answer:

30 square feet

Step-by-step explanation:

Level 1 : Length = 5 ft ; Width = 2 ft

Level 2 : Length = 6 ft ; Width = 2 ft

Level 3 : Length = 4 ft ; Width = 2 ft

Area = L x W

Level 1 = 5 ft * 2 ft = 10 ft²

Level 2 = 6 ft * 2 ft = 12 ft²

Level 3 = 4 ft * 2 ft =   8 ft²

Total Area                30 ft²

Outdoor carpet should measure 30 square feet to cover the hole.

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.
