A rectangle has a length that is 9 feet less than four times its width. Its area is 90 square feet

kramer

Answer:

The length of rectangle is $15\ ft$

The width of rectangle is $6\ ft$

Step-by-step explanation:

Let

x-----> the length of rectangle

y----> the width of rectangle

we know that

The area of rectangle is equal to

$A=xy$

$A=90\ ft^{2}$

$90=xy$ -----> equation A

$x=4y-9$ -----> equation B

substitute equation B in equation A and solve for y

$90=(4y-9)y$

$4y^{2}-9y-90=0$

using a graphing calculator

The solution is

$y=6\ ft$

Find the value of x

$x=4y-9$ -----> $x=4(6)-9=15\ ft$

The logarithm of a quotient can be written as a difference of logarithms:

$\log_3\left(\dfrac uv\right) = \log_3(u) - \log_3(v)$

You can also think of this as a combination of the product-to-sum and reciprocal/power properties of logarithms:

$\log_3\left(\dfrac uv\right) = \log_3\left(u \times \dfrac1v\right) = \log_3(u) + \log_3\left(\dfrac1v\right) = \log_3(u) - \log_3(v)$

To summarize,

$\log_b(mn) = \log_b(m)+\log_b(n)$

$\log_b\left(\dfrac mn\right) = \log_b(m) - \log_b(n)$

$\log_b\left(m^n\right) = n \log_b(m)$
