Solve for d.
6 = d - 16
d =

22

Step-by-step explanation:

Here is our equation:

6 = d - 16

So, to solve this, you have to find d alone.

To accomplish this, you must add 16 to both sides to get rid of the -16(negative sixteen) to find d alone.

So...

6 = d -16

6 + 16 = d -16 + 16

The -16 and + 16 cancel each other out.

So now you are left with

6 + 16 = d

So you add 6 and 16 together to find the answer for d

which is 22!

( 22 = d)

14, 17, 30

Step-by-step explanation:

In order to form a triangle, the sum of two sides must be GREATER than the third side for all combinations:

a + b > c    &    a + c > b     &       b + c > a

21 + 23 = 44 which is NOT greater than 44

2 + 3 = 5 which is NOT greater than 7

12 + 36 = 48 which is NOT greater than 53

14 + 17 > 30     &    14 + 30 > 17       &     17 + 30 > 14

so these side length form a triangle
