Atheater has n rows of seats and the number of seats in each row is 4 less than the number of rows. which of the following represents the total number of seats in the theater (a) n(n-4) (b) n(n-4) (c) n2+4 (d) n(4-n) (e) n2-4

The correct option is a) n(n-4).

Step-by-step explanation:

Consider the provided information.

Let n represents the number of rows.

The number of seats in each row is 4 less than the number of rows.

This can be written as:

A theater has n rows of seats.

Therefore the total number of seats in the theater is:

Hence, the correct option is a) n(n-4).

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
