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

HELP ASAP 40 POINTS
AleksandrR [38]

Given:

The sequence is -8, -12, -16.

To find:

The nth and 52th term  of the given sequence.

Solution:

We have,

-8, -12, -16

It is an AP because the difference between consecutive terms are equal. Here, first term is -8 and the common difference is

r=a_2-a_1

r=-12-(-8)

r=-12+8

r=-4

The nth term of an AP is

a_n=a+(n-1)d

Where, a is first term and d is common difference.

Putting a=-8 and d=-4, we get

a_n=-8+(n-1)(-4)

a_n=-8-4n+4

a_n=-4-4n

Putting n=52, we get

a_{52}=-4-4(52)

a_{52}=-4-208

a_{52}=-212

Therefore, the equation for the nth term of the given sequence is a_n=-4-4n and the 52nd term of the sequence is -212.
