I hope this helps you
m (ACD)=m (ABD)
4x+4=6x-14
2x=18
x=9
m (ACD)=4x+4 =4.9+4=40
Answer:
15÷1 .50=10
Because you are already paying a flat rate of $15. You make 1.50 off of each flower. So you have to sell over 10 flowers to make a profit.
If the polygons are similar, then we can set up a similarity ratio using sides AB and EF and any other 2 sides where both side lengths are given. That appears to be true for sides BC and FG. Our similarity ratio would be this then, going from the bigger polygon stuff on top and the smaller polygon stuff on bottom:
.
If we cross multiply we have 8y = 36 and divide both sides by 8 to get that y = 4.5. There you go!
Answer:
x =2
Step-by-step explanation:
14x - 10 = 3(4 + x)
Distribute
14x -10 = 12 +3x
Subtract 3x from each side
14x -10 -3x = 12+3x-3x
11x -10 = 12
Add 10 to each side
11x -10+10 = 12+10
11x = 22
Divide each side by 11
11x/11 =22/11
x =2
<span>the answer is
sin x +2sin x cos x=0
</span>sin x(1 +2 cos x) =0, so sin x =0 or (1 +2 cos x)=0, implies <span>cos x =-1/2</span><span>
the solutions are x= arc sin 0 = 2Pi +2kpi or x=arccos (-1/2)=2Pi/3 +2kpi</span>
