Answer:
5.5 and 1.2
Step-by-step explanation:
Well all you would have to do is subtract 25 to 5 which is 5 so $20 is how much
8 x² + 14 x + 5 = 0
2 ( 4 x² + 7 x ) = - 5
2 ( 4 x² + 7 x + 49/16 - 49/16 ) = -5
2 ( 4 x² + 7 x + 49/16 ) - 98/16 = - 5
2 ( 2 x + 7/4 )² = - 5 + 98/16
2 ( 2 x + 7/4 )² = -80/16 + 98/16
2 ( 2 x + 7/4 )² = 18/16 = 9/8 / : 2
( 2 x + 7/4 )² = 9/16 / √
2 x + 7/4 = 3/4
2 x = 3/4 - 7/4 = -1
x = - 1
and 2 x + 7/4 = -3/4
2 x = -7/4 - 3/4 = - 10/4= -5/2
x = - 5 / 4
(4/7)-(1/3)
(12/31)-(7/21)
(5/21) is left
Or
In decimal form
(4/7)=0.571
(1/3)= 0.333
0.571-0.333
=0.238
