If i have 7 coin i need to make .24 cent out of the 7 coin

if coins are £1.00 they are 1.00 value if coins are pennys £0.01 they are 0.01 value we simply x the 7.00 (£1's) by the 0.24 = 1.678 and round up to £1.67 of £7

Step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
