Answer:

Step-by-step explanation:

(x+6)(x+3)=9+(x+1)

= x^2+3x+6x+18

=x^2+9x+18=9(x+1)

=x^2+9x+18=9x+9

tbs = to both sides

(-9x tbs)= 9x-9x=0 so x^2+18=9

(-18tbs) = x^2=9-18 becomes x^2=-9

x= $\sqrt{-9}$

M<br> (2y+19)<br> (5x+20)<br> n<br> (4x-11)

AleksandrR [38]

Answer:

(5x+20)+(4x-11)=180(linear pair)

9x+9=180

9x=180-9

9x=171

x=171/9

x=19

now,

(2y+19)+(5x+20)=180(co-interior angle)

2y+19+5×19+20=180

2y+134=180

2y=180

y=180/2

y=90
