The variables x, y, and z represent polynomials where x = a, y = 3a – 5, and z = a2 + 2. what is x2y – z in simplest form?

2a2 – 5a – 2
3a3 – 6a2 – 2
–3a3 – 2
–3a2 – 2

The simplest form of is

Option 2 is correct.

Step-by-step explanation:

Given: The variables X, Y, and Z represent polynomials.

We need to find

Substitute the value of X, Y and Z into expression

Combine the like term

Simplest form is

Hence, The simplest form of is

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
