Which are steps the could be used to slove 0=9(x2+6x)-18 by completing the square

Elis [28]

Answer:

(x+3)²-11=0

Step-by-step explanation:

0=9(x2+6x)-18

0= 9x² +54x-18

0= 9( x²+6x-2) taking 9 common

0= x² +6x-2 (breaking the mid term to find the second element of the square

0 = (x)² +2(x)(3) +(3)² -2 -9 adding and subtracting the second element

0= (x+3)² -11 summing up

In the adjoining figure, area of trangle ABC is

Zepler [3.9K]

Answer:

$PQ=4\ cm$

Step-by-step explanation:

see the attached figure with the letter D to better understand the problem

we know that

The segment side AD is the height of triangle ABC

so

Triangles PBQ and ABD are similar by AA Similarity Theorem

The area of triangle ABC is equal to

$A=\frac{1}{2}(BC)(AD)$

we have

$A=48\ cm^2\\BC=12\ cm$

substitute

$48=\frac{1}{2}(12)(AD)$

$AD=8\ cm$

Remember that

If two triangles are similar then the ratio of its corresponding sides is proportional

so

$\frac{BP}{AB}=\frac{PQ}{AD}$

substitute the given values

$\frac{BP}{2BP}=\frac{PQ}{8}$

$\frac{1}{2}=\frac{PQ}{8}$

$PQ=4\ cm$
