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
Answer:
(-1,5) (3, 1/125)
Step-by-step explanation:
I used desmos to graph the equation then the points attached you will see the screenshot so you can be sure. The points are the same color as the circle on the left side of the point. Hope this helps!
Answer:
Jamie has 11/15 yards of Green Felt more than Blue Felt
Step-by-step explanation:
Green felt- Blue felt
= 5/6- 1/10
= 25/30- 3/30 ( taking LCM)
= 25 - 3/30
=22/30
=11/15 yards
LCM= 2*3*5= 30
Factors of 6= 2*3
Factors of 10= 2*5
Answer:
2 and 3 look similar to A
1, 4, 5 and 6 are not similar to A .
hopefully you got it right.
