Answer:

-2

Step-by-step explanation:

Subtracting a negative number is the same as adding it, so this is basically just negative 8 plus 6, which is -2. Don't know who was right though, you kinda left that part of the question out.

The two triangles are similar, What is the length of DE?
horsena [70]
<h2>Answer:</h2>

This is easy. All you need to do is set up a <u><em>proportional relationship</em></u>.

A proportional relationship uses variables to show similarities, in this case, in triangles.

\frac{2}{3} = \frac{x}{6.3}\\\\3x = 12.6\\\\x = 4.2

<u><em>x</em></u> represents the missing side.

F(x)=3x-2<br>Simplify F(2x)-F(x+2)​
inysia [295]

Answer:

3x - 6

Step-by-step explanation:

To evaluate f(2x) and f(x + 2) substitute x = 2x and x = x + 2 into f(x)

f(2x) = 3(2x) - 2 = 6x - 2

f(x + 2) = 3(x + 2) - 2 = 3x + 6 - 2 = 3x + 4

Thus

f(2x) - f(x + 2)

= 6x - 2 - (3x + 4)

= 6x - 2 - 3x - 4

= 3x - 6
