Answer:

12.2 cm

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as obtuse, scalene, equilateral and isosceles triangle. We say that two triangles are similar if the ratio of their corresponding sides are equal and their corresponding angles are also equal.

Since both triangles are similar, then the ratio of their corresponding sides are equal. Hence:

$\frac{x}{18} =\frac{17}{25} \\\\x=\frac{17}{25} *18\\\\x=12.2\ cm$

VashaNatasha [74]

Suppose there are 12 equal parts of the house to be cleaned. Max can do 1 per hour, and Maggie can do 3 per hour.

The number of units they can do together in x hours is x+3x. Since there are 12 units to do, x+3x=12. For x=3 this is true, so the sister was right!

Answer:

$\large\boxed{D.\ 2x^2y\sqrt[5]{7xy^3}}$

Step-by-step explanation:

$\sqrt[5]{224x^{11}y^8}\\\\=\sqrt[5]{(32)(7)x^{5+5+1}y^{5+3}}\\\\\text{use}\ a^na^m=a^{n+m}\\\\=\sqrt[5]{(2^5)(7)x^5x^5x^1y^5y^3}\\\\\text{use}\ \sqrt[n]{ab}=\sqrt[n]{a}\cdot\sqrt[n]{b}\\\\=\sqrt[5]{2^5}\cdot\sqrt[5]{x^5}\cdot\sqrt[5]{x^5}\cdot\sqrt[5]{y^5}\cdot\sqrt[5]{7xy^3}\\\\\text{use}\ \sqrt[n]{a^n}=a\\\\=2\cdot x\cdot x\cdot y\cdot\sqrt[5]{7xy^3}\\\\=2x^2y\sqrt[5]{7xy^3}$
