PLS HELP ASAP NEED THIS NOW

Answer:

Step-by-step explanation:

<h3>Numerator</h3>

(3x)(3x) = 9x^2

√9x^2 = 3x

Numerator = 3x

<h3>Denominator</h3>

√18y^2 = √18 · √y^2

√18 = 3√2

√y^2 = y

3√2y

Denominator = 3√2y

Now we need to rationalize the denominator, and get rid of the square root on the bottom

$\frac{3x}{3\sqrt{2} y}$ * $\frac{3\sqrt{2} }{3\sqrt{2}}$ = $\frac{6x\sqrt{2} }{12y}$ = $\frac{x\sqrt{2} }{2y}$

Uhhhhhh????????????!

Answer:

2y + 3 = 4y + 2; y = 1/2

Step-by-step explanation:

to find this equation we can use the ys and the 1s to create an equation

in the left side

there are 2 ys and 3 1s

your equation is

2y + 3

on the other side

it is

4 ys and 2 1s

4y + 2 is your equation

then yo uset them equal to each other

2y + 3 = 4y + 2

if you must solve

subtract 2y and 2 from both sides

1 = 2y

then divide both sides by 2

y = 1/2 is your answer
