Answer:

Step-by-step explanation:

So add the x's together then add the others

So x + 7x = 8x

Then 3 + 2 = 5

= 8x + 5

The area of a swimming pool is 120 square meters. The width of the pool is 8 meters. What is the length of the pool in centimete

Klio2033 [76]

A=LW We want to solve for L so divide both sides by W

L=A/W, and we are told that A=120 and W=8 so

L=120/8 m

L=15m

(now if that isn't a typo and you actually want the length in cm then)

L=15m(100cm/m)=1500cm

Combine Radicals/Fractional Exponents

$\mathsf{Given :\;\;\dfrac{5x^{\dfrac{-3}{2}}y^{-2}}{\sqrt[3]{64x^3y^3}}}$

$\mathsf{\implies \dfrac{5x^{\dfrac{-3}{2}}y^{-2}}{\sqrt[3]{4^3x^3y^3}}}$

$\mathsf{\implies \dfrac{5x^{\dfrac{-3}{2}}y^{-2}}{\sqrt[3]{(4xy)^3}}}$

$\bigstar\;\;\textsf{We know that : \boxed{\mathsf{\sqrt[n]{a} = a^{\dfrac{1}{n}}}}}$

$\mathsf{\implies \dfrac{5x^{\dfrac{-3}{2}}y^{-2}}{{(4xy)^{\dfrac{3}{3}}}}}$

$\mathsf{\implies \dfrac{5x^{\dfrac{-3}{2}}y^{-2}}{{4xy}}}$

$\mathsf{\implies \left(\dfrac{5}{4}\right) \left(\dfrac{x^{\dfrac{-3}{2}}}{{x}}\right)\left(\dfrac{y^{-2}}{y}\right)}$

$\bigstar\;\;\textsf{We know that : \boxed{\dfrac{a^m}{a^n} = a^{m - n}}}}$

$\mathsf{\implies \left(\dfrac{5}{4}\right) x^{\left(\dfrac{-3}{2} - 1\right)}}y^{(-2 - 1)}}$

$\mathsf{\implies \left(\dfrac{5}{4}\right) x^{\left(\dfrac{-3 - 2}{2}\right)}}y^{-3}}$

$\mathsf{\implies \left(\dfrac{5}{4}\right) x^{\left(\dfrac{-5}{2}\right)}}y^{-3}}$

$\textsf{Comparing the above with $\mathbf{ax^by^c}$, We can notice that :}$

$\bigstar\;\;\mathsf{a = \dfrac{5}{4}}$

$\bigstar\;\;\mathsf{b = \dfrac{-5}{2}}$

$\bigstar\;\;\mathsf{c = -3}$

$\implies \mathsf{Product\;of\;a,\;b\;and\;c = \left(\dfrac{5}{4}\times \dfrac{-5}{2} \times -3\right)}$

$\implies \mathsf{Product\;of\;a,\;b\;and\;c = \dfrac{75}{8}}$

It costs $480.00 to rent an apartment on the Gold Coast for a weekend. Last year it cost $400.00.

LekaFEV [45]

Answer:

The third choice.

(480 - 400) / 400 * 100.

Step-by-step explanation:

(480 - 400) / 400 * 100

= 80/400 * 100

= 1/5 * 100

= 20%.

Which quadratic equation is equivalent to (x2 – 1)2 – 11(x2 – 1) 24 = 0? u2 – 11u 24 = 0 where u = (x2 – 1) (u2)2 – 11(u2) 24 wh

RSB [31]

The equivalent equation of the quadratic equation (x² – 1)² – 11(x² – 1) + 24 = 0 is u² - 11² + 24 = 0

<h3>How to determine the equivalent equation?</h3>

The equation is given as:

(x² – 1)² – 11(x² – 1) + 24 = 0

Let u = x² - 1

So, we have:

u² - 11² + 24 = 0

Hence, the equivalent equation of the quadratic equation (x² – 1)² – 11(x² – 1) + 24 = 0 is u² - 11² + 24 = 0
