Which represents all the values of x that make the rational expression undefined? x = –3 x = 7 x = –7 or x = 7 x = –3 or x = 3

The value of x would be -3.

Step-by-step explanation:

Consider the complete question is,

'Which represents all the values of x that make the rational expression undefined?'

Since, the rational expression is defined for all real values except those for which denominator is equal to zero,

If 3x + 9 = 0,

3x = -9

Hence the values of x that make the rational expression undefined would be -3.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

i would need to see the dot plot : )
