I got x equals 3 and for the who equation I got 30, you can see the work in the picture

The solution of the equation "[tex]x(x+2)+3(x+2)[/tex]" will be "[tex]5(x+3)[/tex]".
According to the question,
- [tex]x(x+2)+3(x+2)[/tex]
and,
- [tex]x+2=5[/tex]
By substituting "5" in place of "(x+2)" in the above given equation i.e.,
[tex]x(x+2)+3(x+2)[/tex], we get
= [tex]x(x+2)+3(x+2)[/tex]
= [tex]x(5)+3(5)[/tex]
By applying multiplication, we get
= [tex]5x+15[/tex]
= [tex]5(x+3)[/tex]
Thus the response above is appropriate.
