Answer:

384 cm^2

Step-by-step explanation:

A = 6a^2    (a = side length)

A = 6(8^2)

A = 6(64)

A = 384 cm^2

More explain stuff:

a^2 is what is used to find the area of a 2 dimensional square. You can also use a · a. Remember, a = side length. Since there are 6 sides/faces in a cube, you multiply the area of each face by 6. :D

A store marks up the price of an item by 20%. What expression represents the cost a customer pays for the item?
ohaa [14]

Answer:

What is the nth term of this sequence 7, 9, 11, 13
Alexus [3.1K]

Answer:

The nth term of the sequence is

<h2>5 + 2n</h2>

Step-by-step explanation:

The sequence above is an arithmetic sequence

For an nth term in an arithmetic sequence

A(n) = a + ( n - 1)d

where a is the first term

n is the number of terms

d is the common difference

From the question

a = 7

d = 9 - 7 = 2 or 11 - 9 = 2

So the nth term for the sequence is

A(n) = 7 + ( n - 1)2

= 7 + 2n - 2

<h3>A(n) = 5 + 2n</h3>

Hope this helps you

The Verrazano Narrows Bridge has a main span of 3,260 feet. The Akashi Kaikyo Bridge has a main span that is about 54% longer. W
zloy xaker [14]

Answer:

Rounding it to the nearest foot, the length of the main span of the Akashi Kaikyo Bridge is 5,020 feet.

Step-by-step explanation:

Given that the Verrazano Narrows Bridge has a main span of 3,260 feet, while the Akashi Kaikyo Bridge has a main span that is about 54% longer, to determine the length of the main span of this last bridge, the following calculation must be performed:

3,260 x 1.54 = X

5,020.4 = X

Thus, rounding it to the nearest foot, the length of the main span of the Akashi Kaikyo Bridge is 5,020 feet.

Which shows the equation y + 2 = 3(x - 2) written in standard form
Law Incorporation [45]

Standard form is ax + by = c.

To change y+2 = 3(x-2) into that form, do:

y+2-2 = 3x -6 -2

-3x + y =  -8

Which is not in the list, so none of the answers are right...
