Using the distributive property, 10x + 20.
(5 * 4) + (5 * 2x) = 20 + 10x = 10x + 20.
3:5 = 64cm
3x+5x= 64
8x=64
x=8
Therefore,
3x=8×3
=24
5x=8×5
=40
3x+5x=64cm
Answer:
<h2>A. -2y+5x/3x-2y</h2>
Step-by-step explanation:
Given the complex fraction;
![-\frac{2}{x} +\frac{5}{y} / \frac{3}{y} - \frac{2}{x} \\](https://tex.z-dn.net/?f=-%5Cfrac%7B2%7D%7Bx%7D%20%2B%5Cfrac%7B5%7D%7By%7D%20%2F%20%5Cfrac%7B3%7D%7By%7D%20-%20%5Cfrac%7B2%7D%7Bx%7D%20%5C%5C)
First we will find the LCM of the numerator and the denominator as shown below;
![\frac{-2y+5x}{xy} /\frac{3x-2y}{xy}](https://tex.z-dn.net/?f=%5Cfrac%7B-2y%2B5x%7D%7Bxy%7D%20%2F%5Cfrac%7B3x-2y%7D%7Bxy%7D)
Then we divide both equation by multiplying the numerator by the reciprocal of the denominator as shown;
![= \frac{-2y+5x}{xy} * \frac{xy}{3x-2y} \\= \frac{-2y+5x}{3x-2y} \\](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B-2y%2B5x%7D%7Bxy%7D%20%2A%20%5Cfrac%7Bxy%7D%7B3x-2y%7D%20%20%5C%5C%3D%20%5Cfrac%7B-2y%2B5x%7D%7B3x-2y%7D%20%5C%5C)
This gives the required answer
A=1/2b(h) this is the formula to find the area of a triangle
