By definition, 3 side lengths are a triangle if any 2 side lengths add up to be greater than the third.
We can already see that the side lengths 6 and 12 will add up to a value of 18, which is equal to the last side length, meaning that the three values are not a triangle.
(Since this is not true, this is not a triangle)
Hope this helps.
頑張って!
The correct answer is D. (3x-4)(x+4).
Answer:The perimeter (length around the entire outside) is twice the length plus twice the width.
Step-by-step explanation: P = 2(L) + 2(W) = 2(12) + 2(10) = 24 + 20 = 44 The perimeter is 44 feet.
