The correct answer is ( a . )
Answer:
35m
Explanation:
Perimeter is the sum of all the sides of a shape, or a+b+c=P.
12m+8m+15m = 35m
2t + 8 ≥ -4(t+1)
PEMDAS
2t + 8 ≥ -4t - 4
2t + 12 ≥ -4t
12 ≥ -6t
-2 ≤ t

Answers: Choice A and Choice C</h3>
Explanation:
Think of the vertical lines as train tracks (the metal rails).
Stuff between the rails are interior angles.
Angles 3 and 6 are one pair of alternate interior angles because they are on alternating sides of the transversal line. The other pair of alternate interior angles are angles 4 and 5.
Alternate interior angles are congruent when we have parallel lines like this.
