Follow the process for establishing a set of equations: 1. Choose a variable to represent one of the unknowns.
2. Express the remaining unknowns in terms of the variable you chose in step 1. Look for a relationship between
the unknowns given in the problem.
3. Write an equation. (Look for the other relationship given in the problem.)
The tens digit of a number is twice the ones digit. The sum of the digits in the number is 12. What is the number?
Include the entire process for establishing a set of equations, the solution, and an explanation of what the solution
means in terms of the variables. Complete your work in the space provided.

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

inverse property is the answer
