Answer:

x = 2

Step-by-step explanation:

We need to find the value of x so that the value of given function becomes 21 .

We have ,

f(x)=21\\\\ f(x)= 6x + 9

Now , for finding x ,

6x +9 = 21 \\\\ 6x = 21 -9 \\\\ 6x = 12 \\\\ x = 2

What is the solution to 6x^2 + 2x + 4 = 0?
Angelina_Jolie [31]

Step 1) Divide 6 and 4 (the last 2 numbers) and bring everything else down

<em>6x^24x+2x+4</em>

Step 2) Place in parentheses

<em>(6x^24x)+(2x+4)</em>

Step 3) Figure out what you can take out of each parentheses.

**In the first one, you can take out 6x because both numbers have x and 6 is the largest number 6 and 24 can go into.**

**In the second one, you can only take out 2 because 2 is the largest number that goes into 2 and 4.**

Step 4) You will know you did it correctly when the parentheses match up

<em>6x(x+4) + 2(x+4)</em> <<< this is how it should look

Answer: <em>(6x+2)(x+4)</em>
