Nita will win if Eric chooses 17 and she chooses a number less than 8 (ex. n<8).
Answer:
a. 440
Step-by-step explanation:
The information provided allows us to set up the following system of linear equations:

We already have the value for A, solving the system gives us the values for B and C:

The total number of forms used is:

He used 440 forms.
Answer:
50.24 yards
Step-by-step explanation:
We will use the pythagorean theorem to find hypotenuse of each of the 4 triangles.
Pythagorean Theorem is 
For Spinach area, two of the legs are 8 and 6. Solving for hypotenuse:

For watermelon area, two of the legs are 12 and 8. Solving for hypotenuse:

in red peppers area, the hypotenuse is already given as 15. But we need to find one leg since that will be the leg of the triangle in tomatoes area. Hypotenuse is 15 and one leg is 12, so the other leg is:

So, in tomatoes area, we have one leg 9 and another leg 6. Solving for hypotenuse:

Adding all the four hypotenuses, we get the length of the walkway:
Length of Walkway =
yards
It’s a 7% increase. When you want to find percent increase/decrease, you want to subtract the numbers of the before and after. In this case, subtract 1926 and 1800, which will equal 126. Then, percent over 100 would be the first fraction, but since you don’t know the percent, put x. The second fraction is the amount of change over the original number. In this case, the amount of change will be 126 and the original is 1800. x/100=126/1800 now you just cross multiply and solve. You will end up with 7
