Answer:
12x+19.95=13x+9.95
19.95=x+9.95
10=x
So after 10 classes the cost will be the same
12(10)+19.95=120+19.95= $139.95
13(10)=9.95=130+9.95= $139.95
Answer:
3x^{4} + 4x³ + 5x - 6
Step-by-step explanation:
Given in the question is an expression
(3x³ - 2x² + 4x - 3)(x + 2)
Apply distributive law
(3x³ - 2x² + 4x - 3)(x) + (2)(3x³ - 2x² + 4x - 3)
3
- 2x³ + 4x² -3x + 6x³ - 4x² + 8x - 6
Rearrange the like terms
3
+ x³(-2+6) +x²(4-4) +x(-3+8) - 6
3
+ 4x³ + 5x - 6
After performing indicated operation the result is
