The expression for the perimeter would be
2(x) + 2(2x+7)
which can be simplified to 2x+4x+14
which equals 6x+14

Answer:
2 nickels, 9 dimes
Step-by-step explanation:
When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the <em>unshaded</em> area the solution space. Here, the vertices of the triangular solution space are ...
(2, 9), (2, 13), (6, 9)
Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.

Three solutions are shown:
(x, y) = (2, 9), (3, 10), (4, 11)
We are given with the costs: 4$ entrance fee and 3$ per pound of pumpkin picked. The total amount of costs is represented by the function: y = 4 + 3x where y is the total cost of a person entering the patch and x is the number of pounds of pupmkin bought.
Answer: 30° and 330°
<u>Step-by-step explanation:</u>
sec θ = 
sec θ = 
= 
cos θ = 
cos θ = 
cos θ = 
cos θ = 
Look at the Unit Circle to see that cos =
at 30° and 330° ( which is equivalent to π/6 and 11π/6)
