Answer:
Option D
Step-by-step explanation:
In the first three options we can evaluate the values of x with the help of Sine Rule for all the triangles
The Rule says

Where a , b and c are the sides opposite to the angles A, B and C of any ΔABC.
Hence , in order to determine unknown values of sides or angles , we need any 3 values from all 3 sides and 3 angles in a triangle. First Three options give us three values but the last option gives only 2.
Example
in first option we can apply Sine Rule as





GCF = -c^2d^3
Factors are -c^2d^3(8c^3d^3 + 27c^2d + 24)
Sarahtime (min) {3 } 5 12 17
distance (meters) {75} 125 300 425
Eva time (min) {2} 7 10 20
distance (meters) {52} 182 260 520
Sarah:meters over min =75 over 3 = 25 over 1
25 meters per min
Eva :meters over min= 52 over 2 =26 over 1
26 meters per min
eva is the faster swimming because 26 meters per min is faster then 25 meters per min .
i hope this help
