B= 2000 + CD
98000 = B + CD
substitute b in
98000 = 2000 + CD + CD
add variables
98000 = 2000 + 2CD
subtract 2000 from each side
96000 = 2CD
divide each side by 2
48000 = CD
3 0s because 7 times 5000 equals 35000
Answer:
{y|y≥0}
Step-by-step explanation:
The parent absolute value function is

This is a V-shaped function whose vertex is at the origin.
This means that, the least y-value is 0 and there is no highest y-value.
The range refers to all y-values for which the function exists.
Therefore the range is

Or
{y|y≥0}
Assuming you're asking for the area and the length is 52 ft...
52 x 9 = 468
