Answer: -3x² - 2x -57

This is how this would look: \frac{x+2}{2x-6} - \frac{x+3}{5x-15}

First I brought the denominator to the top for both expressions.

so I was left with: 2x-6(x+2) - 5x-15(x+3)

I distributed, combined like terms, and simplified.

<em><u> -3x² - 2x -57</u></em> was my answer

Step-by-step explanation:

The expression sin 50 cos 40 + cos 50 sin 40 is equivalent to
enyata [817]
Sin (a+b) = sin a. cos b + cos a. sin b

a= 50° and b=40°, then

sin(50+40) = sin 50° . cos 40° + cos 50° . sin 40°

sin(50+40) = sin 90° = 1 and

sin 50° . cos 40° + cos 50° . sin 40° = 1

MrMuchimi

Simplifying the expression gives 13/ 36

<h3>How to solve the expression</h3>

Given;

1/4(1-2/3)^2+1/3

Represented as;

\frac{1}{4} * ( 1  - \frac{2}3} )^2 + \frac{1}{3}

Take the LCM of the bracket

\frac{1}{4} * ( \frac{1}{3} )^2 + \frac{1}{3}

Find the square

\frac{1}{4} (\frac{1}{9} )+ \frac{1}{3}

Find the LCM

\frac{1}{36} + \frac{1}{3}

1 + 12/36

13/ 36

Thus, simplifying the expression gives 13/ 36
