X^2+4x+4=8
-8 -8
subtract 8 from both sides
x^2+4x-4=0
now factor using quadratic formula
ax^2+bx+c=0
x= -b +-[ (sqrt (b^2-4ac))/2a ]
x=-2(1+sqrt(2))
x= 2(sqrt(2) -1)
hope that helps, hopefully you know how to plug and chug into quadratic formula. if not you can ask for help
Answer:
4
Step-by-step explanation:
okay since there was a 50% INCREASE, 6 is (100%+50%) greater than last months amount.
100%+50%=150%=1.5
let's say that x is last months amount
6=1.5x
x=6/1.5
x=4
There were 4 musicians in the band last month.
<span>trapezoid JKLM is translated according to the rule (x, y) → (x + 8, y − 3)
</span><span> the coordinates of point L' are
</span> (-2, -5) → (-2 + 8, -5 − 3)
(6, -8)
the answer is
<span> d. (6, −8)</span>

Angles in a quadilateral 360
2 + 3+4+6 =15
2/15 × 360° =48°
3/15 × 360° = 72°
4/15 × 360° = 96°
6/15 × 360° = 144°
