The volume of a box is given by the expression

Kamila [148]

Answer:

Area = x^2+4x+3

Step-by-step explanation:

The volume of a box is given by the expression

x^3 + 3x^2 - x-3. The height of the box is given by the expression x-1.

volume of the box = Length * width * height

L is the side length of the box;

Given

V(x) = x^3 + 3x^2 - x-3

Factorize

V(x) = x^2(x+3)-1(x+3)

V(x) = (x^2-1)(x+3)

V(x) = (x+1)(x-1)(x+3)

V = LWH

V = Area * Width

Since the height of the box is x - 1

Area = (x+1)(x+3)

Expand

Area = x^2+3x+x+3

Area = x^2+4x+3

A square has a diagonal length of 10 ft. Draw a diagram and determine the perimeter of the square.

denpristay [2]

The perimeter of the square is: $20\sqrt2$ ft

Step-by-step explanation:

The picture is attached with the answer.

the diagonal of a square divides it into two right angled-triangles.

We can use one of the triangle to find the length of side as the diagonal will be the hypotenuse of the triangle

Let a be the side of the square, then according to Pythagoras theorem

$d^2=a^2+a^2\\(10)^2 = 2a^2\\2a^2=100$

Dividing both sides by 2

$\frac{2a^2}{2}=\frac{100}{2}\\a^2=50$

Taking Square root on both sides

$\sqrt{a^2}=\sqrt{50}\\a=\sqrt{25*2}\\a=\sqrt{5^2 * 2}\\a=5\sqrt{2}\ ft$

Now,

$P = 4a\\P = 4 * 5\sqrt{2}\\=20\sqrt{2}\ ft$

Hence,

The perimeter of the square is: $20\sqrt2$ ft
