The ceiling of Xavier’s living room is a square that is 12 ft long on each side. To decorate for a party, he plans to hang crepe paper around the perimeter of the ceiling and then from each corner to the opposite corner.
Xavier can buy rolls that each contain 10 ft of crepe paper. What is the minimum number of rolls he should
buy? Show all your work

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

the olimpics is not going to wokk out

step-by-step explanation:

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
