Answer: The expression for number of faces of a pyramid =1+n
Step-by-step explanation:
A Pyramid is a polyhedron or a three dimensional shape having a polygon base and all lateral faces are triangles .
Its base describe the number of other faces of it.
For example a triangular pyramid has a triangular base which gives rise to 3 lateral faces , and a rectangular pyramid has a rectangular base which give rise to 4 lateral faces and so on.....
So the total number of faces in a pyramid = base + lateral faces
If a pyramid has n sides therefore it give rise to n lateral faces such that
The total number of faces in a pyramid= 1+n .
Answer:
594
Step-by-step explanation:
22*3=66
66*3=198
198*3=594
-12 < -6x
-12/-6 > x divide both sides by -6
12/6 > x two negatives makes a positive
2 > x simplify
x < 2 switch sides
hope this helps, God bless!
Answer:
a) 3(x+2)
b) 13y+12
Step-by-step explanation:
3x+6 divide by six and put the rest in parenthesis 3x/3=x 6/3=2
3(x+2)
13+14y-1-y
rearrange so like terms are next to each other
13-1+14y-y
combine like terms
12+13y
it would be 0, because in the origin equations, the d's cancel out since it's x-x, only 2 would be left, therefore the correct answer is A since 0+2=2
