Answer:
<h3>4x = - 12 - 28</h3>
Step-by-step explanation:
When we transpose - 4x to the LHS then it becomes positive i.e +4x
Now we transpose 28 to the RHS then it becomes negative i.e - 28
So the first step you have to is,
<em>4x = - 12 - 28</em>

We have been given a Quadratic equation, where we have to find the real values of x ~
So, let's proceed with middle term splitting method :




Now, we have two conditions here~
Either (x + 6) = 0

or (x - 1) = 0

Answer:
<em>Hi there!</em>
<u><em>For 1. it should be answer b</em></u>
<u><em>For 2. it would be answer c</em></u>
<u><em>For 3. it is answer a</em></u>

Note that (5π)/6 radians = 150°. Therefore the given angle is in quadrant 2.
Refer to the figure shown below.
Reference angles are measured relative to the horizontal axis.
Therefore the reference angle in each quadrant is π/6 radians or 30°.
Denote the reference angle as θ'.
Then, in quadrant 1,
cos θ' = √3/2, sin θ' = 1/2, tan θ' = √3.
Because we are in quadrant 2,
sin θ' = π/6;
sin(5π/6) is positive, but cos (5π/6) and tan (5π/6) are negative.
Answer:
5π/6 is in quadrant 2.
The reference angle, θ' = π/6.
sin(5π/6) is positive, cosine and tangent are negative.
Answer:
25
Step-by-step explanation:

Cross Multiply
16.25 x 100 = 65x
1625 = 65x
1625 = 
x = 25
