Maznah had a piece of ribbon of length 2m she used 1/4 of the ribbon totie her hair and 1/2 of the ribon to tie a parcel . a) what was the total length of the ribbon used ? b) what was the length of the ribbon left?

Step-by-step explanation:

The total length of the ribbon is 2 meters. She used 1/4 of the ribbon to tie her hair. This means that the length of the ribbon that she used in tying her hair is 1/4×2 = 1/2 meter

She used 1/2 of the ribbon to tie a parcel. This means that the length of the ribbon that she used in tying the parcel is 1/2×2 = 1 meter

A) The length of total ribbon used will be 1/2 + 1 = 3/2 meters

B) the length of ribbon left would be total length - length of ribbon used. It becomes

2 - 3/2 = 1/2 meters

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
