Answer:

x^2 + y^2 + 6x - 8y + 21= 0.

Step-by-step explanation:

The center of this circle is (-3, 4) and the radius id 2.

So in Standard form, the equation is:

(x + 3)^2 + ( y - 4)^2 = 2^2

Converting to General form we have:

x^2 + 6x + 9 + y^2 - 8y + 16 = 4

x^2 + y^2 + 6x - 8y + 9 + 16 - 4 = 0

x^2 + y^2 + 6x - 8y + 21= 0.

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:-

$\longrightarrow\sf{7x-21}$

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

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

Answer:

±3/5

Step-by-step explanation:
