Simply add all of it together.
13+6=19
19+8=27
27+7=34
34 is the perimeter
Answer:
The Percent change is -30% (decrease)
In this case we have a negative change (decrease) of -30 percent because the new value is smaller than the old value.
Step-by-step explanation:
Here, To find the percentage change, use this formula
<h3>
<u>Formula</u>:</h3>
Percent change = New - Old ÷ |Old| × 100%
Percent change = 210 - 300 ÷ |300| × 100%
Percent change = -90/300 × 100%
Percent change = -30% (decrease)
Thus, The Percent change is -30% (decrease)

Step-by-step explanation:
The equation of a circle in general form is
x² + y² + 2gx + 2fy + c = 0
with centre = (- g, - f) and radius = 
Given
2x² + 2y² + 6x - 8y + 12 = 0 ← divide through by 2
x² + y² + 3x - 4y + 6 = 0 ← in general form
Compare like terms
2g = 3 ⇒ g = 
2f = - 4 ⇒ f = - 2 and c = 6, thus
centre = ( -
, 2 ) and
radius =
