The lenght of a rectangle is 4 cm less than three times the width. the perimeter is 64 cm
dybincka [34]
Let the width be x cm.
Then length=3x-4 cm.
Its perimeter is 64 cm.
We know that perimeter of a rectangle= 2(length+width)
So,
2(3x-4+x)=64
6x-8+2x=64
6x+2x=64+8
8x=72
x=9
Therefore,
length=(3×9-4)cm=(27-4)cm=23 cm.
Width=9 cm.

Exponents solve this for 50 points and brainlist
Zepler [3.9K]

Answer:

<u></u>\frac{10m^{10}n^{6}p^{9}}{y}

Step-by-step explanation:

Simplifying the numerator :

⇒ (-5m⁷n⁰p⁵)(2m⁴n³p²)³

⇒ (-5m⁷p⁵)(8m¹²n⁹p⁶)

⇒ (-5)(8)(m)⁷⁺¹²n⁹(p)⁵⁺⁶

⇒ <u>-40m¹⁹n⁹p¹¹</u>

<u />

Dividing by the denominator :

⇒ \frac{-40m^{19}n^{9} p^{11}  }{-4m^{9}n^{3}p^{2}y} }

⇒ \frac{10m^{10}n^{6}p^{9}}{y}
