<h3>Answer: 1350 square cm</h3>

===============================================

Explanation:

Each face of the cube is a square with side length 15. The area of the square is s^2 = 15^2 = 225. There are 6 faces, so 6*225 = 1350

------

In terms of a formula, the surface area of a cube is

SA = 6s^2

plugging in s = 15 gives

SA = 6*15^2

SA = 6*225

SA = 1350

Basically it's the same sort of steps as before.

goblinko [34]

Answer:

Step-by-step explanation

Answer:

4x^2-5x+1=0

=4x^2-x-4x+1=0

The second 4x is because of 5x=-x-4x

=xmultiply(4x-1)-4x-1)=0

=(4x-1)x(x-1)=0

=4x-1=0

Another value for x is

x-1=0

Final

=x=1/4

=x=1

Finally the answers are

Value of first X is

X=1/4

Value of second X is

X=1
