Monomial: expression with one term
Example: 6x
Binomial: expression with two terms
Example: 6x + 7
Trinomial: expression with three terms
Example: 8x^2 + 6x + 7
*any expression with four or more terms will be called a polynomial*
<u>Answer:</u>
The sale price per piece of chicken was $0.69
<u>Step-by-step explanation:</u>
• We have to first calculate the price of 1 piece of chicken when 12 pieces cost $9.48.
Original price per piece = $9.48 ÷ 12
= $0.79
• According to the question the price per piece decreased by $0.10 during the sale.
∴ Sale price per piece = $0.79 - $0.10
= $0.69
