Answer:
Subject 's' in terms of 't'
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<u><em>Given that the subject 't in terms are 's'</em></u>
Given that t = 5 s +4
subtracting '4' on both sides, we get
t - 4 = 5s +4-4
t - 4 = 5 s
Dividing '5' on both sides ,we get
The skew lines are two lines that are not parallel but they do not intersect
so the answer is C.
