When using the inspection method, which number would you add to (and subtract from) the constant term of the numerator in this expression so the polynomial in the numerator will have (x 4) as a factor?

To be able to factor x + 4 from the last two terms, you need the unit coefficient to be 4 x 18 = 72, so you need to add and subtract 68: 
(x + 4)x + 18x + 4 + 68 - 68 
(x + 4)x + 18x + 72 - 68 
(x + 4)x + (x + 4)18 - 68 

So you end up with: 
(x + 4)(x + 18) - 68 

 
Add and subtract 68

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
