I believe that the answer is 1845

the surface area of the cube is 1350

the surface area of the pyramid is 495

the total surface area is :
$1350 + 495 = 1845$

good luck

You are designing a wall Mural that will be composed of squares of different sizes. One of the requirements of your design is th

Oxana [17]

Answer:

1. Area of a square = (x^2)^2 = x^4

(each side is x^2, area of a square = side^2

so (x^2)(x^2) = x^4 )

2. when x = 5

area = 5^4 = 625

3. when x = 10

area = 10^4 = 10000

Step-by-step explanation:

Hope its right!

What is the formula for the following arithmetic sequence?

vlabodo [156]

$a_{n}$ = 12 + (- 6)(n - 1 )

This is an arithmetic sequence with n th term

$a_{n}$ = $a_{1}$ + (n - 1)d

here d = - 6 - 0 = 0 - 6 = 6 - 12 = -6 and $a_{1}$ = 12, hence

$a_{n}$ = 12 + (- 6)(n - 1)

use this formula to find the 30 th term

$a_{30}$ = 12 + (- 6 × 29) = 12 - 174 = - 162
