Two similar cylinders have volumes of 480cm3 and 60cm3.
a) Find the fully simplified ratio of the volume of the larger cylinder to the volume of the smaller cylinder. (Answer : 8:1 )

b) Using the answer to part (a), find the ratio of the height of the larger cylinder to the height of the smaller cylinder.

a,480 over 60=80cm3

b,(c over 24)the whole cubed=480 over 60

c*60=24*480

c=11520/60

=192

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.
