Rationalize the denominator of the following expression and simplify:
Mama L [17]
To "rationalize the denominator" is another way to say, getting rid of that pesky radical at the bottom.

we'll simply start by multiplying top and bottom by the "conjugate" of the denominator, recall difference of squares, anyhow, let's do so

\bf \cfrac{6+\sqrt{2}}{5-\sqrt{2}}\cdot \cfrac{5+\sqrt{2}}{5+\sqrt{2}}\implies \cfrac{(6+\sqrt{2})(5+\sqrt{2})}{(5-\sqrt{2})(5+\sqrt{2})}\implies \cfrac{(6+\sqrt{2})(5+\sqrt{2})}{5^2-(\sqrt{2})^2}
\\\\\\
\cfrac{30+6\sqrt{2}+5\sqrt{2}+(\sqrt{2})^2}{25-2}\implies \cfrac{30+11\sqrt{2}+2}{23}\implies \cfrac{32+11\sqrt{2}}{23}

The area of a triangle is 1440cm^2 the base of tge triangle is 5 times the height of the triangle
Oduvanchick [21]
What should we find...
Probably base and the height...

Area = 1440cm²

base = 5×height

base = 5h

Area of triangle = base × height

1440 = 1/2 × 5h × h

1440 = 5h²/2

5h² = 2880

h² = 2880/5

h² = 576

h=24cm..

Height = 24cm

Since base = 5h

Base = 5×24

Base = 120cm...

Hope this helped....

Base =
