Question

Use the condition of $400 given to find the area in terms of only the variable x, and make a reasonable closed interval to use for the variable x.

Options:
a) x>10
b) x<20
c) 5d) x=400

Answer 1

To find the area in terms of only the variable x, set up an equation using the given condition of $400. The area in terms of x is 400. The reasonable closed interval to use for x is d) x=400.

Step-by-step explanation:

To find the area in terms of only the variable x, we need to use the information given. Since we are given the condition of $400, we can set up an equation: 400 = x. This means that x represents the value of $400. The area in terms of x would be 400.

Since x represents the value of $400, the reasonable closed interval to use for the variable x would be d) x=400. This means that the only possible value for x is 400.
