(x+11) (2x+6) 70
set up and sole an equation and find the value of x
show work too
i really need

Well,

(x+11)(2x+6)=180

You can either use the Foil Method, or the Box Method, any works.

So, x*2x=2x^2,  x*6=6x, 11*2=22x, and 11*6=66

So,now, your equation is 2x^2+28x+66=180

Take 180 away to set the equation equal to 0.

Making it look like this,

2x^2+28x-114=0

You can't find x using the normal method to factor, so use the Quadratic Formula.

Once applied, you should get this equation,

x= -7+√106 and x= -7-√106

Once you've done that,

x≈ 3.29563014 and x≈ -17.29563014.
