(I’m currently on mobile so sorry for possible bad formatting)

First, recall the trig identity: tan(A-B)=(tan(A)-tan(B))/(1+tan(A)tan(B))

We see that the given equation directly corresponds with this, with A=9x and B=5x.

Thus we can equate the given equation to tan(9x-5x)=tan(4x)
This cannot be simplified further.

Answer:  tan(14x)

<u>Step-by-step explanation:</u>

Consider the Sum Formula for tan:

tan(A + B)=\dfrac{tan(A)+tan(B)}{1-tan(A)(tan(B)}\\\\\\tan(9x+5x)=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}\\\\\\\large\boxed{tan(14x)}=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}

Which postulate proves these two triangles are congruent?
Korvikt [17]

Answer:

C. HL

Step-by-step explanation:

Since both triangles have a congruent hypotenuse (they share the same hypotenuse) and both have a 90° angle, with a congruent leg, then the postulate that proves these two triangles are congruent, would be the HL (hypotenuse leg) postulate.

- A company produces 7,200 gallons of
Mice21 [21]

Answer:

Number of gallons of water produced each cay by the company = 7200 gallons

Number of 1 gallon bottles put in a carton = 8

Number of cartons needed to hold all the 1 gallon bottles in a day = 7200/8

                                                                                                         = 900

So 900 cartons are required to hold all the one gallon bottles produced by the company in a day. I hope the procedure is clear enough for you to understand. It is also important to carefully look at all the details that are provided in the question.

What is the value of x in -5x-(-7-4x)-2(3x-4)
Otrada [13]

Answer:

x = 1

Step-by-step explanation:

-5x-(-7-4x)-2(3x-4)

-5x + 7 - 4x - 6x + 8          First step is to factor all the numbers out so you have          no parenthesis. In this case -(-7 just turns into + 7 because two negatives equal a positive. As well as -2*3x and -2*-4 which gives you -6x + 8.

-15x + 15                            In this step you combine like terms.

-15x = -15                            Next you move the whole number to the other side of the equation by subtracting it from both sides.

x = 1                                     Finally you divide -15 by -15 to get x by its self.
