Acube has an edge length of 2x. write an expression for the total area of the cube.

Step-by-step explanation:

The Total Surface Area of a cube is given by the formula;

If the cube has an edge length of then, .

When we put this value into the formula we obtain the Total Surface Area in terms of to be

This simplifies to;

This finally gives us

The correct answer is,

expression for the total area of the cube = 24x²

Step-by-step explanation:

Formula:-

Area of cube = 6a²

Where a is the side length of cube.

To find the area of cube

Here edge length, a = 2x

Total area =  6a² = 6 * (2x)²

 = 6 * 4 * x²

 = 24x²

Therefore the area of given cube with edge length  2x is 24x²

This question is incomplete, here is the complete question:

Suppose in the next year, 2007, College D's expenses and enrollment remain about the same, but in addition to their current revenues, they receive an additional $50,000,000 grant. This would allow them to reduce average tuition by how much?

A) $1388.89

B) $3571.43

C) $5555.56

D) $9500.00

E) $25888.89

number of students = 36,000

A) $

1388.89

Step-by-step explanation:

the college received additional grant which is $50,000,000

and the number of students is 36,000,

and we also know that expenses and enrollment remained the same.

So if we have more money (grants) and nothing changed (expenses remain the same)

dividing the grant by the number of students will show just how much the average tuition fee would be reduced

therefore R = G/n

R = 50,000,000 / 36000

R = 1,388.888 ≈  $1388.89
