B) 41"
If the legs of 41" are 9" less than half the base, the base is:
(41-9) 2 = 64
All sides of the triangle added together (perimeter):
41" + 41" + 64" = 146"
Hope this helps! ~ArchimedesEleven

How to divide and simplify this radical expression

Evgen [1.6K]

Answer:

$\dfrac{2x}{5}\sqrt[3]{50x^2}$

Step-by-step explanation:

Since the root indices are the same, the fraction can be combined under one radical. Then you want to do two things:

factor out perfect cubes
make the denominator a perfect cube (so it can be factored out)

$\displaystyle\dfrac{\sqrt[3]{16x^8y^2}}{\sqrt[3]{5x^3y^2}}=\sqrt[3]{\dfrac{16x^8y^2}{5x^3y^2}}=\sqrt[3]{\dfrac{16x^5}{5}}=\sqrt[3]{\dfrac{(2x)^3\cdot2\cdot5^2x^2}{5^3}}\\\\=\boxed{\dfrac{2x}{5}\sqrt[3]{50x^2}}$
