(3x-4y)^2-(3x-4y)(3x+4y)

zheka24 [161]

Answer:

$-24xy + 32y^2$

Step-by-step explanation:

Hello!

We can use the special binomial product formulas:

$(a + b)^2 = a^2 + 2ab + b^2$
$(a + b)(a - b) = a^2 - b^2$

<h3>Simplify</h3>

$(3x - 4y)^2 - (3x - 4y)(3x + 4y)$
$(9x^2-24xy+16y^2) - (9x^2 - 16y^2)$
$9x^2 - 9x^2 - 24xy + 16y^2 + 16y^2$
$-24xy + 32y^2$

The simplified form is $-24xy + 32y^2$

Write the equation 2y-4x=5 In the form y=my+b

Vika [28.1K]

Answer:

y = 2x + 2.5

Step-by-step explanation:

To begin, we start with the equation 2y - 4x = 5.

We will add 4x to both sides to move the x term to the right side of the equation, giving us:

2y - 4x + 4x = 4x + 5

2y = 4x + 5

Next, we should divide by 2 to cancel out the coefficient on the y-term and isolate it on the left side of the equation:

2y/2 = 4x/2 + 5/2

y = 2x + 5/2

Therefore, your answer is y = 2x + 5/2 or y = 2x + 2.5.

Hope this helps!
