Answer:

$\boxed{\sf \ \ \ 248 \ \ \ }$

Step-by-step explanation:

Hello,

$(fog)(4)=f(g(4)) \ \ \ and \ \ \ g(4)=-6*4^2+9*4+9=-51 \ \ so\\(fog)(4)=f(-51)=-5*(-51)-7=255-7=248$

hope this helps

If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed?

Lynna [10]

There are 6, you'd think there would be 8 but the answer is actually 6. A diagonal is a line segment that connects to vertices, the two vertices chosen do not count when forming the triangle, two vertices that are adjacent to that chosen vertex are NOT included when forming the diagonal. It's confusing, but I hope this helps. If you have any follow up questions I'd love to answer them.
