I will give you a explanation about how I got the answer!
Plus, I'm am so sorry if I answer this so long...
Hope It Helped! :)
F(9)
sub 9 forx
f(9)=5(9)-16
f(9)=45-16
f(9)=29
f(9)=29
B) because the rate of change is 7, while for A the rate of change is 6 and for C and D the rate of change is 4
Answer:
<e & <g are vertical
<e & <a are corresponding
<e & <a are alternate interior angles
<g & <a are alternate exterior angles
<g & <f are none of the above
ur welcome. have a great day
Well, notice the composite is really just 4 triangles atop sitting on top of 4 rectangles, and all of them area stacked up at the edges.
so, for the rectangle's sides,
front and back are two 6x3 rectangles
left and right are two 6x3 rectangles
the bottom part is a 6x6 rectangle
now, we don't include the 6x6 rectangle that's touching the triangles, because that's inside area, and is not SURFACE area, so we nevermind that one.
now, the triangles are just four triangles with a base of 6, and a height of 4, in red noted there.
so, just get the area of all those rectangles and the triangles, sum them up and that's the
surface area of the composite,
