In order to join a karate class, you have to pay $10 for registration and then $2 per class. Find the equation that determines the total amount spent. T = total, c = class

2c + 10 = T

Step-by-step explanation:

Since you already have to pay $10, then that would just be added.

Then it is $2 per class: 2c

So 2c + 10 = the total cost

2c + 10 = T

Hope this helped :)

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

are ya tryin to ask something or is this a statement
