Answer:

18 units.

Step-by-step explanation:

A classic right triangle is the 3, 4, 5 triangle. Essentially, 3^2 + 4^2 = 5^2 . Otherwise known as, 9 +16 = 25. With that said, there are two of those that we can make by drawing horizontal lines along the grid. We also know from counting the two vertical sides are each 4 units. To summarize, two sides are 5 units and two are 4 units. We add them together, 5 + 5 + 4 + 4 = 18

Answer:

394.67 minutes (or about 6.58 hours)

Step-by-step explanation:

For 145.8 feet long fence:

At a rate of 2.25 feet per minute, its gonna take him

$\frac{145.8}{2.25}=64.8$ minutes to pain

Also

At a rate of 0.75 feet per minute, its gonna take him

$\frac{145.8}{0.75}=194.4$ minutes to stain

For 76.2 feet long fence:

At a rate of 2.25 feet per minute, its going to take him

$\frac{76.2}{2.25}=33.87$ minutes to pain

At a rate of 0.75 feet per minute, its gonna take him

$\frac{76.2}{0.75}=101.6$ minutes to stain

In total, it's gonna take him:

64.8 + 194.4 + 33.87 + 101.6 = 394.67 minutes

In hours, that is 394.67/60 = 6.58 hours

Part A:

We see that this pair of equations has 1 solution. On a graph, the solutions of 2 (or more) lines is where the lines intersect. In this case, since these lines intersect 1 time, they have 1 solution.

Part B:

As previously mentioned, the solutions of multiple lines is where the lines intersect. In this case, since they intersect at (4,4), that is the solution.
