So when X is 0, the area of the pool is 1200. That makes A and C impossible... then you can plug in numbers...say the boardwalk is 1 ft wide, add 2 to each dimension and plug in 1 for X. (You're adding 2 because there is a tile on either side of each dimension, including corners).
32x42=1344=4+140+1200
Therefore the answer is B.
By substitution.
Get y or x alone then insert it into the other equation solving for one of the two variables. After that substitute ur answer into one of the equations then solve.
Answer:
The median is 8.5
Step-by-step explanation:
When you find the median of an even amount of number, you add the two middle numbers and divide by 2.
There are 64 options available.
To find this answer, we just have to multiply all of the possibilities for each choice. This is the fundamental counting principle.
The are 4 sizes, 2 crusts and 8 toppings.
4 x 2 x 8 = 64
