The measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x.Write an equation that would allow you to solve for the value of x.

Solve for the value of x

Answers

Answer 1
Answer: You know that all the angles are going to add up to equal 360 degrees. So x+2x+3x+(did you mean 4x?)=360

Assuming you meant 4x on the last part, that simplifies to 10x=360
So x=36

Choose the triangle that seems to be congruent to the given one.AFD =~ ____

AFC
BFC
DFE

Answers

Answer:

The triangle that seems to be congruent to triangle AFD is triangle AFC.

Step-by-step explanation:

As in the give triangle AFD, there is an obtuse angle, i.e angle AFD is obtuse angle.

So, in order to have a congruent triangle, the another triangle must have an obtuse angle.

From the given triangles, only triangle AFC has an obtuse angle and that is angle AFC. And they also share a side, so the chances of congruency is more in this case.

Triangle BFC and Triangle DFE does not have an obtuse angle.
AFD is equivalent to AFC.

They are the same size, shape, length, and angles.

What are the solutions of the equation 9x4 – 2x2 – 7 = 0? Use u substitution to solve.

Answers

U substitution uses the variable "u" as a replacement for another variable. In this case, we will substitute in u for x^2. Since u=x^2 we can now rewrite the equation. 9u^2 -2u -7. This is factored to (u-1)(9u+7). Now put x^2 back in for u. (x^2 -1)(9x^2 +7). Factor again. (x-1)(x+1)(9x^2 + 7). Since 9x^2 + 7 doesn't factor, we don't bother with it any more.The answer is x=1 or x=-1.

               x(x² + 3x + 9) - 3(x² + 3x + 9) = 0
                                (x - 3)(x² + 3x + 9) = 0

                        x = 3                              2(1)
                                           x = -3 ± √(9 - 36)

                                           x = -1.5 + 1.5i√(3) or x = -1.5 - 1.5i√(3)

In each step I have to factor the equation to a trinomial so that it could be factored into the sums and differences of cubes. Then, I have to use the quadratic equation in order to find the two solutions of the second factor, which is equal to -1.5 + 1.5i√(3) and -1.5 - 1.5i√(3), while on the first factor I have to find the solution to the first factor, making the solution equal to 3. So the solutions to the polynomial equation are the numbers 3, -1.5 + 1.5i√(3), and -1.5 - 1.5i√(3).

Solution Set: {3, -1.5 ± 1.5i√(3)}

Smither thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers and assigns each group the same task (in this case, they’re supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, Smither counts how many stacks of papers each group has made. The above experiment could be made more valid by _____. Choose the best answer • running a pretrial or using existing data from a time when nobody drinks the juice as a baseline. • increasing the number of groups to 4 with 25 people in each group. • using coconut water instead of juice. • testing the subjects for longer periods of time

Answers

Answer:

The experiment could be made more valid by:

• Running a pretrial or using existing data from a time when nobody drinks the juice as a baseline.

This option would help establish a baseline productivity level for the workers before introducing the special juice. By comparing the performance of Group A (given the special juice) with the baseline performance, it would be easier to determine whether the special juice indeed had an impact on productivity. This approach helps control for any external factors that may affect productivity, making the experiment more valid and the results more reliable.
The best answer is: running a pretrial or using existing data from a time when nobody drinks the juice as a baseline.
This would make the experiment more valid because it establishes a baseline for comparison. By comparing the productivity of both groups with no juice consumption, any differences observed in productivity between Group A (given the special juice) and Group B (not given the special juice) can be more confidently attributed to the juice itself rather than other factors. This helps to ensure that any observed effects are indeed caused by the special juice and not due to other variables or random chance.
