We can first turn the text into a proper formula:

x plus 10 plus 6 x plus 2 x

x+10+6x+2x

The like terms are the numbers with

We can then put the like terms together to continue the calculation:

x+6x+2x+10

=9x + 10

Therefore, the answer is 9x + 10.

katrin2010 [14]

The score of Raven is 9 points

<em><u>Solution:</u></em>

Let the point scored by bangal be"x"

Score of Raven = 40 points

Given that,

The ravens scored 13 more than three times number points that the bangals scored in their last game

Score of raven = 13 + 3(score of bangal)

40 = 13 + 3x

Solve the above equation for x

3x = 40 - 13

3x = 27

x = 9

Thus the score of Raven is 9 points

<u><em>The complete question is</em></u>

The first three steps of completing the square to solve the quadratic equation x2 +4x -6= 0, are shown below.

Step 1: x2 +4x= 6

Step 2: x2 +4x+4=6+4

Step 3: (x +2)^2=10

What are the next 3 steps?​

we have

step 4

Take square root both sides

\sqrt{(x+2)^2} =\sqrt{10}

step 5

Simplify

x+2=\pm\sqrt{10}

step 6

Solve for x

subtract 2 both sides

x=-2\pm\sqrt{10}

x_1=-2+\sqrt{10}

x_2=-2-\sqrt{10}

Solve y + -7 = 13 ?
ratelena [41]
Well first off if you have a negative sign in front of the seven, DO NOT have a plus sign because it will be confusing. So y-7=13? , You add 7 to 13 and = 20, so y= 20
