Answer:

$\frac{3}{500}$

Step-by-step explanation:

Start by converting 5 meters to centimeters. Note 1 meter = 100 centimeters.

We can set up a unit converter:

$5m(\frac{100cm}{1m})$

The meters cancel out leaving us with:

$5*100cm=500cm$

The scale factor is:

$\frac{drawing}{real\ life}=\frac{3cm}{500cm}=\frac{3}{500}$

Answer:

x=3

Step-by-step explanation:

I am assuming that your equation is:

$\sqrt{8x + 12} + 4 = 10$

Subtract 4 from both sides to get:

$\sqrt{8x + 12} = 6$

Square both sides to get:

$(\sqrt{8x + 12})^{2} = {6}^{2}$

$8x + 12 =3 6$

$8x =24$

Divide both sides by 8 to get:

$x = \frac{24}{8} = 3$

The answer is C, because 2 shapes can have the same area, but that doesn't necessarily mean they're congruent.

First one right gets BRAINLIEST!! If f(x)=x²+2x-3 and g(x)=x²-9, find (f/g) 4 and (f+g)(4)

Rasek [7]

Answer:

3 and 28

Step-by-step explanation:

note ( $\frac{f}{g}$ )(x ) = $\frac{f(x)}{g(x)}$

$\frac{f(x)}{g(x)}$

= $\frac{x^2+2x-3}{x^2-9}$ and

( $\frac{f}{g}$ )(4) = $\frac{4^2+2(4)-3}{4^2-9}$ = $\frac{16+8-3}{16-9}$ = $\frac{21}{7}$ = 3

-------------------------------------------------------

(f + g)(x) = f(x) + g(x)

f(x) + g(x)

= x² + 2x - 3 + x² - 9 = 2x² + 2x - 12 and

(f + g)(4) = 2(4)² + 2(4) - 12 = 2(16) + 8 - 12 = 32 + 8 - 12 = 28
