But that doesn't seem to be right.

Dennis plans to use 1150 ft of fence to enclose the rectangular pasture. One side borders a river where there is already a thick hedge it needs no fencing.
The diagram is a rectangle with width x.

a. let x be the width. write an expression for the length in term of x
b. write an expression for the area of the pasture in terms of x
c. suppose the pasture must enclose at least 60,000 sq ft. write a sentence (as a sentence in math not a sentence like this one.) relating the area expression in part b to the area the pasture must enclose.

I have a and b but i want to check them since they're related and i completely don't understand c, can you clear thing sup a bit for me?

I just wanted to check my answer to anyone who's willing to answer it... (PS an explanation would be extremely helpful!!)

Identify the domain of the function give by g(x) = [Square Root of (x+1)] all divided by (x^2 +4x +5) .
What if anything can you deduce about the range?

How do you solve:
angle AOC = 7x-2, angle AOB= 2x+8, angle BOC= 3x+14
And it says to solve for x, but how am I supposed to do that with three of them and nothing to set them equal to? Thanks.

Ramon delivers packages for his job. He visited his work and picked up "some" packages. His instructions were to drop off 1/2 of those packages at a second building and pick up two more packages. His third stop he dropped off 1/2 of his packages and picked up seven. His fourth stop he dropped off 1/4 of his packages and picked up one. On his fifth stop he left 1/2 of his packages and picked up one. On His last stop he dropped off 6 packages, thats all he had left. Then he took lunch break. How many packages did Ramon deliver before lunch? Please leave order of steps you took to receive your answer.

I have a trigonometry quiz tomorrow. We aren't allowed to use a calculator, just our unit circle which has degrees, coordinates, the location and numbers such as 5pi/6.

How do you find Sin, Csc, Cos, Sec, Tan and Cot using this unit circle? Thanks!!
