Alright so if you know to do volume this should be a breeze!

First off what you want to do is find the volume of the outside prism.

V=whl=4·5·8=160

160

Then find the smaller prisms volume.

V=whl=1·5·4=20

Minus the smaller from the bigger

160-20=140

Elliot has a total of 26 books. He has 12 more fiction books than nonfiction books. Let x represent the number of fiction books

inysia [295]

Luckily for us, this problem solved the bulk of its own question!

Now, all we have to do is solve for "x", or the amount of fiction books and plug its value back into the original equation to find the value of "y", or the amount of nonfiction books.

2x = 38

x = 19

There are 19 fiction books.

x + y = 26

19 + y = 26

y = 7

There are 7 nonfiction books.

Hope this helps!

Solve for x. x2 = 100 A. -200, 200 B. -100, 100 C. -50, 50 D. -10, 10

ICE Princess25 [194]

Answer:

D. -10, 10

Step-by-step explanation:

Instead of inserting values into x to solve, let's isolate x.

In order to do this, we must take the square root of both sides.

$\sqrt{x^{2} } =\sqrt{100}$

$x=\sqrt{100}$

To find the square root of 100, we must figure out what = 100 when multiplied by itself. Reminder, it can be both a positive or a negative square root, as positive times positive is a positive, and negative times negative is a positive.

The square root of 100 is -10 or 10, as 10 x 10 or -10 x -10 = 100.

Hope this helps! :)
