Equation is the mathematical statement that two expression are equal. The total number of cucumber plant, planted by Carlos is 10.
Given information-
This year, Carlos planted 6 more than one-third of the cucumber plants he planted last year.
The total number of cucumber plants he planted last year is 12.
Convert the statements given in the problem in the form of equation to find the number of cucumber plant.
What is mathematical equation?
Equation is the mathematical statement that two expression are equal.
Suppose Carlos planted x plants this year. As Carlos planted 6 more than one-third of the cucumber plants he planted last year and the total number of cucumber plants he planted last year is 12. Thus,
Hence the total number of cucumber plant, planted by Carlos is 10.

The correct statement regarding the operations with polynomials is given as follows:
C. (10x³ + 2x² - 11) + 9x² + 2x - 2 = 10x³ + 11x² + 2x - 13.
What are like terms?
Like terms are terms that share these two features:
- Same letters. (algebraic variables).
- Same exponents.
If two terms are like terms, then they can be either added or subtracted, that is, we can use them to simplify a polynomial.
Hence the polynomial that is correctly simplified in this problem is given as follows:
(10x³ + 2x² - 11) + 9x² + 2x - 2 = 10x³ + 2x² + 9x² + 2x - 11 - 3 = 10x³ + 11x² + 2x - 13.
Meaning that option C is the correct option in the context of this problem.

Final answer:
The two numbers that multiply to 24 and add to 2 are -4 and -6. You can find these through the process of elimination with the equations x*y=24 and x+y=2.
Explanation:
The two numbers that multiply to 24 and add to 2 are -4 and -6. Let's find out how:
- First, you should write down the equation based on the question, x*y=24 (x and y are the two numbers).
- Then, form another equation according to the question, x+y=2.
- Now, solve these two equations. With some trial and error, you will find the two numbers are -4 and -6, because (-4)*(-6)=24 and -4+-6=2.
Note that the two numbers are negative which is why they add to a positive number when multiplied.
