The solving for the first one should be like this
And the next part
After these manipulations just multiply them
And finally you need to square and simplify for the completed answer
• 69/20
• 3 9/20
-I can’t see the last one but i’m pretty sure those are the only two

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)
Answer:
Step-by-step explanation:
56/4=16
P=16+16+12+12=56
A=16*12=192 ft^2
For example, y = k/x; when x = 3 => k = 3y; when y = 9 => k = 27 and x = 27/9 = 3;
The answer is 3!
