umka21 [38]

Answer:

Following are the solution to the given question.

Step-by-step explanation:

Please find the graph file and its solution in the attachment.  

4x-15=3x+28\\\\4x-3x=28+15\\\\x=43\\\\

Similarly:

3y+5=2y+50\\\\3y-2y=-5+50\\\\y=45\\\\

For point 1:\to KR=4x-15= 4\times 43-15=172-15=157

For point 2: \to BR=2y+50= 2\times 43+50=86+50=136

For point 3:\to BE=KR=157

For point 4:\to Kf=BR=130

For point 5:\to ERK=KFB=180^{\circ} -\angle B-\angle ERB = 180^{\circ}-92^{\circ}-18^{\circ}=70^{\circ}

55. If 3x = 4y, the value of (x + y)^2 : (x - y)^2 is:<br>​
ladessa [460]

Answer:

\large\boxed{(x+y)^2:(x-y)^2=49}

Step-by-step explanation:

3x=4y\qquad\text{subtract}\ 3y\ \text{from both sides}\\\\3x-3y=y\qquad\text{distributive}\\\\3(x-y)=y\qquad\text{divide both sides by 3}\\\\x-y=\dfrac{y}{3}\qquad(*)\\------------------\\3x=4y\qquad\text{add}\ 3y\ \text{to both sides}\\\\3x+3y=7y\qquad\text{distributive}\\\\3(x+y)=7y\qquad\text{divide both sides by 3}\\\\x+y=\dfrac{7y}{3}\qquad(**)\\------------------

(x+y)^2:(x-y)^2=\dfrac{(x+y)^2}{(x-y)^2}\qquad\text{use}\ \left(\dfrac{a}{b}\right)^n=\dfrac{a^n}{b^n}\\\\=\left(\dfrac{x+y}{x-y}\right)^2\qquad\text{substitute}\ (*)\ \text{and}\ (**)\\\\=\left(\dfrac{\frac{7y}{3}}{\frac{y}{3}}\right)^2=\left(\dfrac{7y}{3}\cdot\dfrac{3}{y}\right)^2\qquad\text{cancel}\ 3\ \text{and}\ y\\\\=(7)^2=49
