Answer:  \textsf{9x}^2\textsf{ - 12x + 4}

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

Given:  \textsf{(3x - 2)}^2

Find: \textsf{Simplify the expression}

Solution:  It looks like 2 is at the end of the parenthesis where the power would be instead of distributing the number.  If so the following steps would be followed.

<u>Expand</u>

  • \textsf{(3x - 2)}^2
  • \textsf{(3x - 2)(3x - 2)}
  • \textsf{(3x * 3x) + (3x * (-2)) + (3x * (-2)) + (-2 * (-2))}

<u>Simplify</u>

  • \textsf{9x}^2\textsf{ - 6x - 6x + 4}
  • \textsf{9x}^2\textsf{ - 12x + 4}

Therefore, after following the provided information we are able to determine that the expanded form would be 9x^2 - 12x + 4.

Answer:

5,000 + 800 + 20 + 9

Step-by-step explanation:

The definition of expanded form is to "write the value of each digit then add them together to find the sum." - study.com

That is exactly what we did above.

If we write it going up and down like below, we can pull the individual values:

5 000

8 00

If you had a slope of 3 and a y-intercept of 2, the equation should be
Lady bird [3.3K]

Answer:

y=3x+2

Step-by-step explanation:

There is enough information to make a equation in slope-intercept form.

y=mx+b

'm' is the slope. 'b' is the y-intercept.  

In the given question, 3 is the slope and 2 is the y-intercept. This means that:

m = 3

b = 2

Plug in the appropriate values:

y=mx+b\rightarrow\boxed{y=3x+2}

Hope this helps.

3x + 8 = -x + 20 What is x?
g100num [7]
First, lets take all the x values on one side.

3x + x + 8 = -x + x + 20
4x + 8 = 20

Now, lets put the numbers on the other side.

4x + 8 - 8 = 20 - 8
4x = 12
x = 3

Hope this helps!
