h - length of the hypotenuse

Use the Pyhagorean theorem:

$h^2=5^2+12^2\\\\h^2=25+144\\\\h^2=169\to h=\sqrt{169}\\\\\boxed{h=13}$

I really need help with this question!

Same as all the other ones like this.

Since the two figures are similar . . .

-- The ratio of of their volumes is R³ .

-- The ratio of their surface areas is R² .

-- The ratio of their dimensions is R .

So R³ is 729 / 2744 .

Take the cube root of that and you'll have R .

Then square R and you'll have the ratio of their surface areas.

How to write y-2=-1/3 (x+6) in standard form and why PLZ HELP

stich3 [128]

$y-2=-\frac{1}{3}(x+6)\\y=-\frac{1}{3}(x+6)+2$

Simply move -2 to another side.

$y=-\frac{x}{3}-2+2$

Distribute -1/3 in (x+6)

$y=-\frac{x}{3}$ ---> Answer
