Which of these numbers is the most precise approximation of square root of 12
A. 3.0
B. 3.446
C. 3.46
D. 3.464

a (for a more specific answer, most likely c)

the reason not to choose 3.464 is because that is the square root of 12 but approximations are usually whole numbers.

sine

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.
