2 8.2 cm 7.7 7.7 cm A clay bowl is in the shape of a hollow hemisphere. Diagram NOT accurately drawn The external radius of the bowl is 8.2 cm. The internal radius of the bowl is 7.7 cm Both measurements are correct to the nearest 0.1 cm. The upper bound for the volume of clay is k(pi) cm3. Find the exact value of k.

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.
