Answer:
900.
Step-by-step explanation:
1) the initial area is: A₀=0.5*base*h;
2) the final area is: A=0.5*(5*base)*(5*h).
It means, that 25A₀=A, then A=900 [cm²].
1. + and - are inverses as well as × and ÷
2. They are equivalent because x equals -3 in each equation.
3. x-3=6 because x=9 in this equation whereas it equals 6 in all of the other ones

Answer:
![(5x^{4} + 9x^{3} + 6x^{2} + 1x)](https://tex.z-dn.net/?f=%285x%5E%7B4%7D%20%2B%209x%5E%7B3%7D%20%2B%206x%5E%7B2%7D%20%20%2B%201x%29)
Step-by-step explanation:
![(5x^{3} + 9x^{2} + 6x + 1) * x](https://tex.z-dn.net/?f=%285x%5E%7B3%7D%20%2B%209x%5E%7B2%7D%20%2B%206x%20%2B%201%29%20%2A%20x)
Multiplying the term by x, adds 1 to the power.
EG
![5x^{3} * x = 5x^{3+1} = 5x^{4}](https://tex.z-dn.net/?f=5x%5E%7B3%7D%20%2A%20x%20%3D%205x%5E%7B3%2B1%7D%20%3D%205x%5E%7B4%7D)
Therefore
![(5x^{3} + 9x^{2} + 6x + 1) * =\\(5x^{4} + 9x^{3} + 6x^{2} + 1x)](https://tex.z-dn.net/?f=%285x%5E%7B3%7D%20%2B%209x%5E%7B2%7D%20%2B%206x%20%2B%201%29%20%2A%20%3D%5C%5C%285x%5E%7B4%7D%20%2B%209x%5E%7B3%7D%20%2B%206x%5E%7B2%7D%20%20%2B%201x%29)
