Answer:

3x^2 -2x+1

Step-by-step explanation:

5x^2 -2x+2 -(2x^2 +1)

Distribute the minus sign

5x^2 -2x+2 -2x^2 -1=

3x^2 -2x+1

Remember the large squares are x^2 , the rectangle are x and the small squares are 1

The colored tiles are positive and the white tiles are negative

5x^2 -2x+2  is 5 colored large squares, 2 white rectangles 2 colored small squares

-2x^2 -1  is 2 white large squares and 1 white small square

Add them together

3x^2 -2x+1  3 colored large squares, 2 white squares and 1 colored small square

suter [353]

Answer:

"Spin the spinner 5 times with 4 equal segments. One of the segment represents vanilla on either the spinner as well as three parts reflect certain flavors" would be the right answer.

Step-by-step explanation:

The actual probability of the given scenario will be:

⇒  (1-\frac{1}{4})^5

⇒  (1-0.25)^5

⇒  (0.75)^5

On solving the power, we get

⇒  (0.237304)

Now on multiplying the above value in 100, we get

⇒  23.73%

Approximately 23.73% chance vanilla was not chosen by either of the five. So that the above is the right answer.

In the figure, the angles are formed by a transversal and two parallel lines. Which angles are congruent?
RUDIKE [14]

Answer:

A is your correct answer.

1, 3, 5, and 7 are equal to each other and 2, 4, 6, and 8 are equal to each other.

Step-by-step explanation:

Congruent angles are angles that have the same measure. In this example, where two parallel lines are cut by a transversal line, the angles in the same position on the top line and bottom line are congruent. For example, angle 1 and 5 are in the same position, so they have the same measure.

Also, vertical angles (opposite angles, like 5 & 7 in your example) have the same measure.

Please let me know if you have questions about this.
