Answer:
The following are parts of a cone:
Vertex , Base , Slant height
Step-by-step explanation:
A cone is formed when one end of a line is rotated about a second fixed line while keeping the line's other end fixed.
The point about which the line is rotated is called a vertex.
and the base of a cone is in the shape of a circle.
Also the curved side that emits from the vertex and joins the circle is called a slant height.
Hence, the terms which are related to parts of a cone are:
Vertex , Base , Slant height

Answer:
-7
Step-by-step explanation:
Lets assume the number Peggy is thinking of be "x".
Now as given, when twice the number is added to three times one more than the number. We can write it as
∴ --- Equation 1
Again, it is given that Peggy gets the same result as when she multiplies four times one less than the number.
∴ -- equation 2
Next, we can equate both the equation 1 and 2 as it is given that result is same.
Let´s distribute 3 into and 4 into
⇒
⇒
Subtract both side by 4x and 3
∴
∴ Peggy was thinking of -7
