Rearrange like terms in this polynomial so like terms are next to each other
mixer [17]

Answer:

4x^2 - 6x^2   -6x + 3x    +3 - 4

Step-by-step explanation:

The terms here involve x^0, x, x^2.

Write the x^2 terms first:  4x^2 - 6x^2;

then write the x terms:  -6x + 3x; and

then write the constants:  3 - 4

and so we have, in descending powers of x,

4x^2 - 6x^2   -6x + 3x    +3 - 4

using a protractor and a ruler draw a right triangle with a side length of 5cm that is beetween the right angle and a 30 degree
Elza [17]

The Triangle will look in this way (Attached image)-

<h3>How do you draw a 30 degree angle with a protractor?</h3>

Step 1: Draw a line segment OQ.

Step 2: Place the center tip of the protractor at point O such that the protractor perfectly aligns with line AQ.

Step 3: Start from 'Q' on the protractor in the anti - clockwise direction and stop at 30. Mark it as point 'P'. If point 'Q' lies to the right of 'O', then start measuring clockwise and stop at 30.

Step 4: Now, place the protector at point Q, mark the point 'P' at 90, such that ∠OQP = 90.

Step 5: Join point 'P' with 'O'. ∠QOP=30° is the required 30 degree angle.
