Answer:

$\large\boxed{\dfrac{36}{25}}$

Step-by-step explanation:

$\text{Use}\ a^{-n}=\dfrac{1}{a^n}\\\\\dfrac{5^{-2}\cdot9}{2^4\cdot4^{-3}}=(5^{-2}\cdot9):(2^4\cdot4^{-3})=\left(\dfrac{1}{5^2}\cdot9\right):\left(2^4\cdot(2^2)^{-3}\right)\\\\\text{use}\ (a^n)^m=a^{nm}\\\\=\left(\dfrac{1}{25}\cdot9\right):(2^4\cdot2^{-6})\\\\\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=\dfrac{9}{25}:2^{4+(-6)}=\dfrac{9}{25}:2^{-2}=\dfrac{9}{25}:\dfrac{1}{2^2}=\dfrac{9}{25}:\dfrac{1}{4}=\dfrac{9}{25}\cdot\dfrac{4}{1}=\dfrac{36}{25}$

The three sides of a triangle are n, 4n−8, and 2n+8. If the perimeter of the triangle is 63 feet, what is the length of each sid

svlad2 [7]

Answer:

9 ft, 28 ft, 26 ft

Step-by-step explanation:

The perimeter is the sum of side lengths, so ...

P = a + b + c

63 = n +(4n -8) +(2n +8) . . . . fill in the given side lengths

63 = 7n . . . . . . simplify

9 = n . . . . . . . . divide by 7

4n -8 = 36 -8 = 28 . . . . second side length

2n +8 = 18 +8 = 26 . . . . third side length

The side lengths are 9 ft, 28 ft, 26 ft..
