Answer:

<h3>            x = 15 cm</h3>

Step-by-step explanation:

If triangle ABC is similar to triangle DEF, then:

                                                                    \dfrac{AC}{DF}=\dfrac{BC}{EF}

Therefore:

\dfrac{x}{5}=\dfrac{12}{4}\\\\\dfrac{x}{5}=3\\\\x=15

If g stands for a whole number, find the first three possible values of g2 + 3.
Sati [7]

So the first three possible values of g^2 + 3 are:

3, 4, 7

The first option is the correct one.

<h3>Which ones are the first three possible values?</h3>

The set of the whole numbers is {0, 1, 2, 3...}

Then the first possible value is when g = 0.

0^2 + 3 = 3

The second possible value is when g = 1

1^2 + 3 = 4

The third possible value is when g = 2.

2^2 + 3 = 7

So the first three possible values of g^2 + 3 are:

3, 4, 7

The first option is the correct one.
