5(x+6)+11=25-3x what is the answer?

1 answer:

3 0

This is how I did it:
$5(x + 6) + 11 = 25 - 3x$ use distribution
$5x + 30 + 11 = 25 - 3x$ use addition
$5x + 41 = 25 - 3x$ use addition and subtraction
$8x = -16$ use division
$x = -16/8$
$x = -2$

So your answer is $x = -2$

The distance between B and C

alina1380 [7]

Answer:

The answer is

<h2> $\sqrt{13} \: \: or \: \: 3.6055 \: \: units$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

B ( 3 , 1 ) and C( 6 , 3)

The distance between them is

$|BC| = \sqrt{( {3 - 6})^{2} + ({1 - 3})^{2} } \\ = \sqrt{ ({ - 3})^{2} + ( { - 2})^{2} } \\ = \sqrt{9 + 4}$

We have the final answer as

$\sqrt{13} \: \: or \: \: 3.6055 \: \: units$

Hope this helps you
