Answer:
D
Step-by-step explanation:
For some side lengths to create a triangle, any two of the side lengths must have an added length together of less than the third leg. Otherwise, the vertices would simply not be able to be connected by the lines. In a), 3+5=8, but since it is not more, the triangle will not be able to be formed (it would basically just be a line.) In B, 7+8< 16. In C, there is the same situation as with the first example (4+15=19). Finally, in the last one, 5+7>12, and all of the side lengths work out. Therefore, the correct answer is D. Hope this helps!
Answer:
312km
Step-by-step explanation:
1. Multiply. 4800 x 7% = 3744
2. Divide. 3744 / 12 = 312km sq.
So the area after 12 years is 312 km sq.
3s is 3 times sydneys age. so the equation would be 3s-5
