A polyhedron is a three dimensional figure in which each side is made up of other two dimensional geometric figures, like triangles, hexagons, etc.
The answer to the question asked, should be 54!
I hope this helps
Not easy to graph but
multily first equaiton by -2 remember to flip sign
-2x+4y>-6
add to other equaiton
2x-2x+y+4y>-6+8
5y>2
divide by 5
y>2/5
subtitute
2x+2/5>8
subtract 2/5 from both sdies
2x>7 3/5
divid eby 2
x>38/10=19/5=3 4/5
x>3 4/5
y>2/5
just shade the area in that zone, not including point (0,0)
Answer:
x=3
Step-by-step explanation:
plug F(2) for x
2(2)^2-5
2^2=4
2(4)-5=x
8-5=3
