Step-by-step explanation:

students in previous year=35

students in next year=42

difference=42-35

Now,

change%=7/42×100%

=16.67%

The question is incomplete. Here is the complete question.

The rectangle bleow has an area of $8x^{5}+12x^{3}+20x^{2}$ . The width of the rectangle is equal to the greatest common monomial factor of $8x^{5},12x^{3},20x^{2}$ . What is the length and width of the rectangle?

Answer: width = $4x^{2}$

length = $2x^{3}+3x+5$

Step-by-step explanation: Greatest common factor is the largest number that will divide into that number without rest, i.e., it's a number that will result in an exact division. The same can be applied to a polynomial.

To find the greatest common factor:

1) Write each in prime factored form:

2.2.2.x.x.x.x.x + 2.2.3.x.x.x + 2.2.5.x.x

2) Identify the common factor among the terms:

For this polynomial, the repetitive factor is $4x^{2}$

Therefore, the width of the rectangle is:

w = $4x^{2}$

Area of a rectangle is the multiplication of width and length, so:

$A=w*l\\l=\frac{A}{w}$
