Determine the possible side lengths of the third side of a triangle with known side lengths 3 and 6. answers: –3 < c < –9
vovangra [49]

Answer:

3 < c < 9

Step-by-step explanation:

The length of a side of a triangle cannot be negative. This eliminates the first and last options.

The addition of two sides of a triangle must be greater than the third side. In this case:

3 + 6 = 9 > c

So, the second option is correct. The third option is not correct, because, for example, c = 8 is possible

I need help solving 12 1/4 - 5 2/3<br> I’m having trouble
Lady_Fox [76]

Answer:

6 7/12

Step-by-step explanation:

We need to get a common denominator, which is 12

12 1/4 - 5 2/3

12 1/4*3/3 - 5 2/3*4/4

12 3/12 - 5 8/12

We will need to borrow from the 12 since 3/12 is less than 8/12.  Write the 1 we borrow as 12/12

11 + 12/12 + 3/12 - 5 8/12

11 15/12 - 5 8/12

6 7/12
