Which of the following is equivalent to the quadratic equation below after completing the square? x^2+4x+1=10

B

Step-by-step explanation:

Given

x² + 4x + 1 = 10 ( subtract 1 from both sides )

x² + 4x = 9

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 9 + 4

(x + 2)² = 13 → B

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

∠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.
