Perform the operation indicated, then place the answer in the proper location on the grid. write your answer in descending powers of x. what must be added to 3x -7 to make x 2 + 4x -1?

x² + x + 6

Step-by-step explanation:

We have to find the expression that must be added to (3x - 7) to make it (x² + 4x - 1).

To get the expression we have to subtract (3x - 7) from (x² + 4x - 1).

Now, (x² + 4x - 1) - (3x - 7)

= x² + x + 6

Therefore, (x² + x + 6) must be added to (3x - 7) to get the result (x² + 4x - 1).

So, the answer is x² + x + 6, which is in the descending power of x. (Answer)

∠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.
