X-25 / x + 13
For this case what you should know is that an indefinite expression are those in which mathematically no numerical value can be obtained.
We have then that a division between zero causes an expression to be undefined.
For x = -13 we have:
(-13-25) / (- 13 + 13) = - 38/0 (undefined)
Answer:
x = -13
d. -13
So, The dots represent the children.
And the numbers represent the length in.
I wouldnt say its D.
I would say its C. Group B, because 4 kids have forearm length longer then 13 in.
The exponent is 6, since 7^6 is the same as (see picture).
