Answer:

9 yards

Step-by-step explanation:

Since both pools are similar, therefore the ratio of their length and width would be equal. That is:

Length of the current swimming pool : length of the new swimming pool = width of the current swimming pool : width of the new swimming pool

Thus, we can set up a proportion as shown below:

Let the width of the new swimming pool be x.

40 : 24 = 15 : x

$\frac{40}{24} = \frac{15}{x}$

Cross multiply

$40*x = 15*24$

$40x = 360$

Divide both sides by 40

$x = \frac{360}{40}$

$x = 9$

The width of the new swimming that is smaller would be 9 yards.

(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 $-24xy + 32y^2$
