The area of a rectangle is(x^2-16)sq cm. if its breadth is(x-4)cm, find its length​

d.192

step-by-step explanation:

12*16=192

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
