Answer: They created Terraces into the mountainside
Explanation:
The Inca dug into the mountain side and created Terraces, which allowed them to filter water down the mountain side, as well as make a steeper ledge, since they did everything by hand, with hand made hoe's made out of branches and stones, they where able to till the ground to plant the seeds. The mountainside dirt was very enriched with minerals, which made it perfect land for farming.

1. x(x+3) = x²+3x
Step by Step:
Apply the Distributive law: (a=x, b=x, c=3)
= xx + x × 3
= xx + 3x
= xx = x²
= x²+3x
-----------------------------------------------------------
2. 3x(4x-7) = 12x²-21x
Step by Step:
Apply the Distributive law: a(b-c) = ab - ac
(a=3x, b=4x, c=7)
= 3x × 4x - 3x × 7
= 3 × 4xx - 3 × 7x
= 12x² - 21x
-----------------------------------------------------------
3. -5x(6x-2) = -30x²+10x
Step by Step:
Apply the Distributive law: a(b-c) = ab - ac
(a = -5x, b = 6x, c = 2)
= -5x × 6x - (-5x) × 2
Apply minus - plus rule: -(-a) = a
= -5x × 6xx + 5 × 2x
= -30x² + 10x
-----------------------------------------------------------
1. x(x+3) = x²+3x
2. 3x(4x-7) = 12x²-21x
3. -5x(6x-2) = -30x² + 10x
Answer:
I'm not sure but i hope this kinda helps
Explanation:
The professionals use their education and professionalism to support the evidence and remain true to the justice system to have a fair trial. The nonprofessional participants are there to either fight for justice for themselves or loved one and on the other side defend themselves.
