There are 100 cm in 1 meter. the dimensions are 400cm by 250cm. depending on which way you turn them, they will fit better. if you take 400 divided by 16, you will have a row of 25 wide and if you divide 250 by 10, you will have a length of 25. you now have 25 rows of 25. 25x25 is 625 tiles.

Use the Distributive Property to simplify the following expression. a: 4(x+2) b; -5(9+x) c: 7(x-3)
ExtremeBDS [4]
<h3>hello!</h3>

=======================================================

The Distributive Property states the following:-

\longrightarrow\sf{a(b+c)=ab+ac

Where

\longrightarrow\sf{a,~b,~and~c~can~be~either~constants~or~variables}

Now, let's use this property to simplify our expressions.

The first one is

\bigstar{\underline{\boxed{{4(x+2)}}}

Simplify by distributing 4:-

\longrightarrow\sf{4~times~x~+4~times~2}

Add the products:-

\longrightarrow\sf{4x+8}

\rule{250}{2}

Solve the next one:-

\bigstar{\underline{\boxed{\sf{-5(9+x)}}}

Distribute -5 & add the products:-

\longrightarrow\sf{-45-5x}

\rule{250}{2}

Solve the last one:-

\bigstar{\underline{\boxed{7(x-3)}}

Distribute 7:-

\longrightarrow\sf{7x-21}

======================================================

<h3>note:-</h3>

Hope everything is clear; if you need any more explanation/clarification, kindly let me know, and I'll comment and/or edit my answer :)

Find the 92nd term of the arithmetic sequence -29, -22, -15, ...
kompoz [17]

Answer:

608

Step-by-step explanation:

The appropriate general formula here is a(n) = a(1) + (n -1)d, where d is the common difference.  Here, d = +7.  Thus:

a(92) = -29 + (92-1)(7) = 608
