Answer:

5x^{2} y

Step-by-step explanation:

A polynomial has a common factor when the same quantity, whether number or letter, is found in all terms of the polynomial.

We can express the terms as follows, and find their common factor.

15x^{2} y^{3}   =  5*5*5*x*x*y*y*ÿ

-20x^{3} yz = -5*5*5*5*x*x*x*y*z

In this way, you can find the elements common to both terms

5x^{2} y(3y^{2} )(-4xz)

In science class, the average score on a lab report is 82 points, with all students scoring within 3.2 points of the average. If
nirvana33 [79]

An equation that represents the minimum and maximum scores is; |x - 82| = 3.2.

<h3>How to write an absolute value equation?</h3>

The absolute value function is defined by:

f(x) = x, x ≥ 0.

f(x) = x, x < 0.

It measures the distance of a point x to the origin.

For this problem, the distance between the minimum and the maximum scores and the mean is of 3.2, that is, the difference between these scores x and the mean of 82 is of 3.2, hence the absolute value equation that represents this situation is given by:

|x - 82| = 3.2.
