Answer: The correct option is (D) 15.6.
Step-by-step explanation: As shown in the attached figure below, W is the mid-point of the line segment VX and WX = 7.8 units.
We are to find the length of the line segment VX.
Since W is the mid-point of line segment VX, so we must have
Since WX = 7.8 units, so VW = 7.8 units.
Therefore, we get
Thus, the length of th eline segment VX is 15.6 units.
Option (D) is CORRECT.

Answer:
Length: 139 feet
Width: 104 feet
Step-by-step explanation:
The formula for the perimeter of a rectangle can be given by . We are given the perimeter of the pool along with the width.
From here, all we have to do is plug back into the original formula:
Which can be further simplified as:
From here, all we have to do is add 70 to both sides of the equation and divide by four:
To make sure that this answer is accurate, we can find that the width of the rectangle should then be 104 (given by 139 - 35). All we have to do is plug back into the original equation:
And the substitution works, so the length of the rectangle would be 139 feet and the width would be 104 feet.
