Answer:
The polynomial function
To determine the multiplicity of 0, -2, -4, 5.
The multiplicity of a root is the number of times the root appears.
First find the root of the equation, set the function equals to zero.
therefore, the root of this function are, x=0,-2, -4, 5
To find the multiplicity of the roots:
A factor of x would have a root at x=0 with multiplicity of 1
similarly, x=-2 with multiplicity of 3
x=-4 with multiplicity of 2
x=5 with multiplicity of 4.
Let and
be, respectively, the length and the width of the rectangle.
If the length is 4 inches more than the width, we have
Moreover, the perimeter of a rectangle is given by
And we can substitute to get
We know that the perimeter is 34 inches:
Which implies
