V<span>ertical angles are equal.
We have 4x = 2x + 18.
Then, 2x = 18;
x = 18 </span>÷ 2;
x = 9 degrees;
The measure of angle DBE is 2 × 9 + 18 = 36 degrees.
Write it in descending order of degree
that is
-g^3 + 6g^2 + 4g - 9
Step-by-step explanation:

First, let's distribute the
variable to each term in the first parenthesis:

Next, let's distribute the
variable to each term in the second parenthesis:

Next, let's group like terms together:

Finally, let's add or subtract like terms to get the result:

The angle of a tangent and a radius is a right angle.
The missing length would be the hypotenuse. Use the Pythagorean theorem to solve.
X = SQRT(12^2 + 16^2)
X = SQRT(144 + 256)
x = SQRT(400)
X = 20
Answer:
-9(7x^5-8)
