<u>Quadratic Equation</u>
A quadratic equation also called a second-degree equation is a special polynomial whose highest degree is two.
The general form of the quadratic equation is
Where a is known as the leading coefficient. Another form to write the quadratic equation is
Where x1 and x2 are the roots or zeroes of the equation.
We have the roots of the given equation are -2 and 2, and the leading coefficient is 3.
Plugging in the given values we have
Operating
Adina did not simply. Before multiplying 5.
If you mean <em>x</em> = 0.666…, then
10<em>x</em> = 6.666…
10<em>x</em> - <em>x</em> = 6.666… - 0.666…
9<em>x</em> = 6
<em>x</em> = 6/9 = 2/3
If you mean <em>x</em> = 0.060606…, then
100<em>x</em> = 6.060606…
100<em>x</em> - <em>x</em> = 6.060606… - 0.060606…
99<em>x</em> = 6
<em>x</em> = 6/99 = 2/33
Answer:
<u>The perimeter of the pentagon ≅ 19 units (approximately)</u>
Step-by-step explanation:
Clockwise, starting from the base of the pentagon, we have:
- Base of the pentagon or bottom side ≅ 4 units
- 2nd side ≅ 3.75 units
- 3rd side ≅ 3.75 units
- 4th side ≅ 3.75 units
- 5th side ≅ 3.75 units
In consequence,
Perimeter of the pentagon ≅ 4 + 3.75 + 3.75 + 3.75 + 3.75
<u>Perimeter of the pentagon ≅ 19 units</u>
