vazorg [7]3 years ago

Answer:

The solution for the given equation is 5.30.

Step-by-step explanation:

The given equation is

745=5x^3

We need to find the solution for the given equation.

Divide both sides by 5.

\frac{745}{5}=\frac{5x^3}{5}

Cancel out common factors.

149=x^3

Taking cube roots on both sides.

\sqrt[3]{149}=\sqrt[n]{x^3}

5.30145919238=x

Interchange the sides.

x=5.30145919238

Approx the answer to the hundredths place.

x\approx 5.30

Therefore, the solution for the given equation is 5.30.

8090 [49]
This is the concept of algebra, let the width be x
height=x-4
length=2x+10
the volume of the box is:
volume=length*width*height
=x(x-4)(2x+10)
expanding the above we get:
(x^2-4x)(2x+10)
=x^2(2x+10)-4x(2x+10)
=2x^3+2x^2-40x=264
solving the above we get real solution will be
x=6
thus we conclude that the width is x=6 inches
length=2*6+10=22 inches
height=x-4=6-4=2 inches
thus the dimension will be:
width=6 inches, length=22 inches, height=2 inches

soldier1979 [14.2K]

The polynomial (a + b)(a² – ab + b²) is reconstructed as (2x + y)(4y² – 2xy + y²), then the correct option is C.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variables are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Tomas learned that the product of the polynomials (a + b)(a² – ab + b²) was a special pattern that would result in a sum of cubes, a³ + b³.

His teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if a = 2x and b = y.

Then the polynomial equation will be

(2x + y)(4y² – 2xy + y²)

More about the polynomial link is given below.
