Step-by-step explanation:
A trapezoid with height 6.4 cm and parallel base is 12.9 cm and 8.6 cm.
We have to find the area of area of this trapezoid.
Area of trapezoid =
Given : Height = 6.4 cm
and parallel base is 12.9 cm and 8.6 cm.
Substitute, we have,
Area of trapezoid =
Simplify, we have,
Area of trapezoid =
Area of trapezoid = 68.8 cm²
Thus, The area of given trapezoid is 68.8 cm²
Using the completing the square method, for the equation, we have the zeros as <u>x = √26 + 4 and x = 4 - √26</u>
<h3>How can the zeros be found using completing the square method?</h3>
The given equation is presented as follows
Which, by completing the square, gives;
The zeros of the equation;
are;

Step-by-step explanation:
Remember that the sum of angles on a straight line are supplementary. (180°)
Therefore 3x + 2 + 6x - 20 = 180.
=> 9x - 18 = 180
=> 9x = 198
=> x = 22.
