Sam is 13 years old and in 8th grade. Sam’s friend Sherry is 13 years old and in 8th grade. Sherry’s friend Tanya is also 13 years old and in 8th grade. Sam concludes that all 13 year olds are in the 8th grade. Determine if Sam’s conclusion is valid. Justify your response by typing in the space provided in the box below this prompt.

It is not valid because some peoples birthday may be late so they will be 12 in 8th grade or some peoples birthday are early so they will be 14 in 8th grade.

Step-by-step explanation:

∠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.

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
