The given figure is a parallelogram find the value of x and y

e-lub [12.9K]

Answer:

Step-by-step explanation:

In a parallelogram, diagonals bisect each other.

7y - 2 = 5y + 4

7y - 2 - 5y = 4

2y - 2 = 4

2y = 4 +2

2y = 6

y = 6/2

y = 3

3x +2 = 23

3x = 23 - 2

3x = 21

x = 21/3

x = 7

Jenna’s weight changed by -3 kg last month. Sarah’s weight changed by 2 1/2kg last month who lost more weight?

Law Incorporation [45]

Hello, I'll try to make this as easy to understand as possible, anyways, let's begin:

First, we know that 3 is a bigger number than 2 1/2, and since it's negative, it means they lost weight, therefore...

Jenna lost more weight than Sarah.

Hope this helped! c:

Solve for x 4/x + 4/x^2-9= 3/x-3

Goshia [24]

$\dfrac{4}{x}+\dfrac{4}{x^2-9}=\dfrac{3}{x-3}\qquad\text{subtract}\ \dfrac{4}{x^2-9}\ \text{from both sides}\\\\\dfrac{4}{x}=\dfrac{3}{x-3}-\dfrac{4}{x^2-9}\qquad\text{use}\ a^2-b^2=(a-b)(a+b)\\\\\dfrac{4}{x}=\dfrac{3}{x-3}-\dfrac{4}{x^2-3^2}\\\\\dfrac{4}{x}=\dfrac{3}{x-3}-\dfrac{4}{(x-3)(x+3)}\\\\\dfrac{4}{x}=\dfrac{3(x+3)}{(x-3)(x+3)}-\dfrac{4}{(x-3)(x+3)}\qquad\text{use distributive property}\\\\\dfrac{4}{x}=\dfrac{3x+9-4}{(x-3)(x+3)}\\\\\dfrac{4}{x}=\dfrac{3x+5}{x^2-9}\qquad\text{cross multiply}$

$4(x^2-9)=x(3x+5)\qquad\text{use distributive property}\\\\4x^2-36=3x^2+5x\qquad\text{subtract}\ 3x^2\ \text{and}\ 5x\ \text{from both sides}\\\\x^2-5x-36=0\\\\x^2-9x+4x-36=0\\\\x(x-9)+4(x-9)=0\\\\(x-9)(x+4)=0\iff x-9=0\ \vee\ x+4=0\\\\\boxed{x=9\ \vee\ x=-4}$
