Answer:

4 times bigger

Step-by-step explanation:

1. The area of an object dilated by a scale factor (SF) will be equal to (SF)^2.

2. For example, let's say the base and height of Triangle A is 4 and 8. The area would be 16 units squared. The base and height of Triangle B would be 8 and 16. The area would be 64 units squared.

3. As you can see from the aforementioned example, the SF (2) was squared and then multiplied by 16 to get 64.

Therefore, Triangle B's area is 4 times bigger than Triangle A's area.

Plot the zeros of this function:<br><br> f(x) = (x – 1)(x – 7).

vredina [299]

Answer:

$\boxed{\mathrm{view \: attachment}}$

Step-by-step explanation:

The zeros of a function is where the function crosses the x-axis. The x-intercepts are the zeros of a function.

$f(x) = (x - 1)(x - 7)$

Let output equal to 0.

$0 = (x - 1)(x - 7)$

Set factors equal to 0.

$x-1=0\\x=1$

$x-7=0\\x=7$

The zeros of the function are $x=1$ and $x=7$ .

Using Triangle Similarity Theorems (6)

Fantom [35]

Answer:

DC = 3

Step-by-step explanation:

Based on triangle similarity theorem, we would have the following equation:

$\frac{AD}{AC} = \frac{AE}{AB}$

Plug in the values

$\frac{9}{9 + DC} = \frac{12}{12 + 4}$

$\frac{9}{9 + DC} = \frac{12}{16}$

$\frac{9}{9 + DC} = \frac{3}{4}$

Cross multiply

3(9 + DC) = 9×4

27 + 3DC = 36

Subtract 27 from each side

3DC = 36 - 27

3DC = 9

Divide both sides by 3

DC = 9/3

DC = 3

What are the solutions to the equation 3x2 + 15x = 18?

jok3333 [9.3K]

$3x {}^{2} + 15x = 18$

<h2>Divide the entire thing by 3</h2>

$x {}^{2} + 5x = 6$

$x {}^{2} + 5x - 6 = 0$

<h2>You can find the roots by using the quadratic formula or by using the form x²-Sx+P</h2>

$let \: \alpha \: and \: \beta \: be \: the \: roots$

<h2>Two numbers whose sum is -5 and product is -6</h2><h2>-6 and +1</h2>

<h2>Your answer is B</h2>
