Answer:
x = -3/2 x=2
Step-by-step explanation:
2x² - x-6=0
Factor
(2x ) (x ) =0
6 = 2*3
2*-2 +3 = -1
(2x +3 ) (x -2 ) =0
2x+3 =0 x-2 =0
2x = -3 x=2
x = -3/2 x=2
6 is the constant of the equation
Answer: B
Step-by-step explanation:
Perimeter = 2(length+width)
'CD' = 20×cos(30) = 17.3205
width 'AD' = 20×cos(60) = 10
Perimeter = 2(17.3205+10)
= 2(27.3205)
= 54.641 =54.6
