Its (x+3)^2 + 4 after conversion to vertex form
Answer:
17 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 2700° , then
180°(n - 2) = 2700° ( divide both sides by 180° )
n - 2 = 15 ( add 2 to both sides )
n = 17
The polygon has 17 sides
Answer:
sum of the first 27 terms = -1431
Step-by-step explanation:
<h3>arithmetic series sum of the first n terms formula:</h3>

n = 27 terms
first term, a = 25
common difference, d = 19 - 25 = -6
substitute the values into the formula





Answer:
4
Step-by-step explanation:
7z^2=112
Divide by 7 on both sides
x^2=16
Take the square root of both sides
x=4
First one: 7/15
Second one : 5/12
