The base of a pyramid has n sides. write an expression for the number of corners on the pyramid.

n+1

If a pyramid has n number of sides

⇒number of vertices in the base = n

Since in a pyramid there is one vertex on the top,and n number of faces are on the sides,and one face is in the base.

Total number of faces of pyramid = n+1

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
