Answer:
Step-by-step explanation:
distribute 2 into (4x+2) and -12 into (x-1)
8x+4=4x-12x+12
combine like terms
8x+4=-8x+12
add -8x on both sides
8x+8x+4=12
16x+4=12
subtract 4 on both sides
16x=8
divide both sides by 16
x=1/2

1,609 meters = 1 mile
10,095 meters = 10,095/1,609 = 6.3 miles
Therefore, <span>10095 meters/seconds = 6.3 miles/seconds</span>
Answer:
x² - 4 x + 3
Step-by-step explanation:
given expression
( x - ( 2 + i ) )( x - ( 2 - i ) )
on solving
= x² - (2 - i )x - (2 + i) x + (2 + i )(2 - i)
= x² - 2 x + i x - 2 x - i x + 2² - i²
using identity
(a+ b)(a-b) = a² - b²
= x² - 4 x + 2 - (-1) ∵ i² = -1
= x² - 4 x + 2 + 1
= x² - 4 x + 3
hence, the required polynomial equation is x² - 4 x + 3
