Answer:
5x
Step-by-step explanation:
got it right on edg
total number of tiles is 6. the number of yellow or purple tiles i 1+3 = 4.
So the probability of a yellow or purple tile is 4/6=2/3
<span>In the question "Susu is solving the quadratic equation 4x2 – 8x – 13 = 0 by completing the square. Her first four steps are shown in the table.
In which step did Susu first make an error?"
Susu made her first error in step 2, when she factored out 4 she is supposed to divide 8x by 4.
Thus the correct expression for step 2 should be 4(x^2 - 2x) = 13
To complete the solution for the equation:
4(x^2 - 2x + 1) = 13 + 4(1)
4(x - 1)^2 = 13 + 4
4(x - 1)^2 = 17
(x - 1)^2 = 17/4
x - 1 = +/- sqrt(17/4)
x = 1 +/- sqrt(17) / 2</span>

<u><em>We need to solve for the angle VXY and it is equivalent to (18x - 2)°. We all know that the total angle of the given figure is 106°, so by adding the angles of the four sides, we can solve for the value of x. The solution is shown below:</em></u></h3>
<em>∠WVX + ∠VXY + ∠XYW + ∠YWV = 360°</em>
<em>Substituting their values, we have:</em>
<em>90° + (12x + 2)° + 90° + (18x -2)° = 360°</em>
<em>Perform addition and subtraction</em>
<em>90 + 12x + 2 +90 + 18x -2 = 360</em>
<em>30x + 180 = 360</em>
<em>Transpose 180 to the right side such as:</em>
<em>30x = 360 -180</em>
<em>30x = 180</em>
<em>Solve for x, we have:</em>
<em>x = 180 / 30</em>
<em>x = 6</em>
<em>Solving for the angle VXY, we have:</em>
<em>∠VXY = 12X + 2 = 12(6) + 2</em>
<em>∠VXY = 74°</em>
<em>The answer is 74°.</em>
