Step-by-step explanation:

x max = 
a = -5
b = 6
-6/2(-5) = 6/10 = 3/5 = .6
.6 thousand = 600
600 speakers should be sold.
Alternatively, you can check the vertex of the parabola formed.
Answer:
29/3 = x
Step-by-step explanation:
Well it’s a 90° angle and it’s separated into two parts, one of which is 56°. To find the other part, you subtract 56 from 90. You should get 34°. Then you set 3x+7 equal to 36°:
3x + 7 = 36
Subtract 7 from both sides:
3x = 29
Divide both sides by 3:
29/3 = x
you cannot simplify this anymore so that is your final answer
