The biggest possible area is one that is as close to a square as possible.
20 ÷ 4 = 5 feet
5 x 5 = 25 ft²
The biggest area is 25 ft² with its length and width at 5 feet.
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The<span> room has square dimensions and it has been built with two pieces of sheetrock, a smaller one and a larger one.
2. Therefore, let's call
x: the smaller one.
y: the larger one.
3. Then, you have that the lenght of the wall is the sum of the smaller one and the larger one:
x+y
4. So, the area of the room is:
(x+y)(x+y)
(x+y)</span>²
Therefore, the answer is: (x+y)²
Answer:
Choice C. The line y =x
Step-by-step explanation:
A function f(x) is symmetric with respect to the y-axis if f(-x) = f(x). If we substitute -x in place of x we end up with a different function. So the function is not symmetric with respect to the y-axis.
Moreover, the function is not symmetric with respect to the x-axis since substituting -y in place of y results into a new function.
If we plot the graph of the function together with the line y =x on the same graph we note that the line y =x acts as a mirror line such that one half of the function lies on the upper end and the other half on the lower end. The function is thus symmetric with respect to the line y =x.
Answer:
x=-2
Step-by-step explanation:
3x-8x = -5x
8+2= 10
5x = 10
simp: x=-2
