Terrible formatting. 0 x 4? What does that mean? - x 0 4? Nobody can read that. I can't even tell what the integral is.

Is 0 x 4 supposed to mean \int_0^x 4 ...?

f(x) = \displaystyle\int_0^x (4 + \sec(2t) ) dt = F(x) - F(0),\ \text{where }F'(x) = 4 + \sec (2t) \\ \\
f'(x) = F'(x) - F'(0)\ \Rightarrow\ f'(x) = 4 + \sec(2x)

Solve the expresssion x − 5 = 17
CaHeK987 [17]

Answer: x = 22

Step-by-step explanation:

We must isolate the x by itself.

We need to add 5 to both sides of the equation so it cancel out from the side with x.

So x = 22
