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: The Roman Republic describes the period in which the city-state of Rome existed as a republican government, from 509 B.C. to 27 B.C. Rome's republican government is one of the earliest examples of representative democracy in the world. Prior to the republic, Etruscan kings who lived nearby in central Italy ruled Rome
