Use the quadratic formula with a = 2, b = -5, and c = 1
x = -b ± sq rt b2 - 4ac
-------------------- <---------- Please note: sq rt is over entire expression of b^2 - 4ac
2a
x = - (-5) ± sq rt (-5)2 + 4(2)(1)
-------------------------------- <---------Please note: sq rt is over entire expression (-5)2 + 4(2)(1)

Answer:
21 to 28
Step-by-step explanation:
Reduce each ratio to lowest terms by dividing by any common factors. (It helps to know your multiplication tables, or a quick way to find the greatest common divisor.)
15 : 20 = (5*3) : (5*4) = 3 : 4
_____
21 : 28 = (7*3) : (7*4) = 3 : 4 . . . . same as 15 : 20
5 : 10 = (5*1) : (5*2) = 1 : 2 . . . . . ≠ 3:4
18 : 25 . . . has no common factors . . . ≠ 3:4

Answer:
8 square units
Step-by-step explanation:
Area of a rectangle= lenght x width
locating the four points on a Cartesian plane
lenght = BC= AD = (0,4)->(4,4) = 4units
width = AB = CD = (0,2)-> (0,4) = 2units
Area of rectangle = 4units x 2units = 8 square units
