Well, lets first start off with combining like terms.
9x + 26 + 7x - 17 = 2x + (-3x) + 5x
9x + 7x + will give you 16x, and 26 - 17 will give you 9. Therefore, the first part of the equation is 16x + 9.
On the other side, you can combine all three terms (2x + 5x - 3x), which will give you 4x.
Using the above steps, you can figure that the answer is 16x +9 = 4x
Answer:

Step-by-step explanation:
So we have the integral:

First, let's use substitution to get rid of the x/2. I'm going to use the variable y. So, let y be x/2. Thus:

Therefore, the integral is:

Now, as you had done, let's expand the tangent term. However, let's do it to the fourth. Thus:

Now, we can use a variation of the trigonometric identity:

So:

Substitute this into the integral. Note that tan^4(x) is the same as (tan^2(x))^2. Thus:

Now, we can use substitution. We will use it for sec(x). Recall what the derivative of secant is. Thus:

Substitute:

Expand the binomial:

Spilt the integral:

Factor out the constant multiple:

Reverse Power Rule:

Simplify:

Distribute the 2:

Substitute back secant for u:

And substitute back 1/2x for y. Therefore:

And, finally, C:

And we're done!
Answer:
no because c, the hypotenuse, should always be larger than a and b added
