Which expression shows the area of the base of each pyramid? (One-fourth x) squared in.2 (One-third x) squared in.2 (One-half x)
777dan777 [17]

Answer:

(a) Area = (\frac{x}{4})^2

Step-by-step explanation:

The question is incomplete. (See comment for complete question).

From the completed question, we have:

Total\ base\ length = x

n = 8 --- number of pyramids

Required

An expression for the area of the base

The total base length of the pyramid represents the perimeter of the base.

And since the base is a square, then the following relationship exist.

Total\ base\ length = 4L

Where L represents the length of each side.

This gives

4L = x

Make L the subject

L = \frac{x}{4}

The area of the base is then calculated as:

Area = L^2

Area = (\frac{x}{4})^2

Which of the following best defines 2 2/3?
inna [77]

Answer:

A. \sqrt[3]{4} = Cube root of 4.

Step-by-step explanation:

We have been given an expression 2^{\frac{2}{3}}. We are asked to find the equivalent expression for our given expression.

Using exponent property \sqrt[n]{a^m} =a^{\frac{m}{n}, we will get,

2^{\frac{2}{3}}=\sqrt[3]{2^2}

2^{\frac{2}{3}}=\sqrt[3]{4}

Upon looking at our given choices, we can see that option A is the correct choice.
