-3x + 6 = 18...subtract 6 from both sides
-3x = 18 - 6
-3x = 12...divide both sides by -3
x = -12/3 reduces to -4 <===
Hi there! :D
<em><u>Answer:</u></em>
<em><u>2(2a+5)</u></em>
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
First, rewrite the problem down 10, and then 4.
10=5*2 or 2*5
4=2*2
2*2a+2*5
Finally you had to factor out by the common term of 2.
2(2a+5)
Hope this helps!

Answer:
The radian is a unit of measure for angles used mainly in trigonometry. It is used instead of degrees. ... As seen in the figure above, a radian is defined by an arc of a circle. The length of the arc is equal to the radius of the circle. Because of this the radian is a fixed size no matter what the size of the circle is.
Step-by-step explanation:
Answer:
a is the _amplitude_(Length of the blades)_
The vertical shift, k, is the _Mill shaft height_


Step-by-step explanation:
In this problem the amplitude of the sinusoidal function is given by the length of the blades.

The mill is 40 feet above the ground, therefore the function must be displaced 40 units up on the y axis. So:

We know that the blades have an angular velocity w = 3 rotations per minute.
One rotation = 
1 minute = 60 sec.
So:


Finally:
a is the _amplitude_(Length of the blades)_
The vertical shift, k, is the _Mill shaft height_
