How many solutions does this system have? x + 2y – 3z = 4
- 2x – 4y + 62 = -8
3x + 6y - 92 = 12
O There is no solution.
• There are an infinite number of solutions.
O There is one solution.
O There are three solutions.

This system has three solutions (D).

Explanation for each of these problems are in the images below.

answer:

c. the third graph

∠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.
