Answer:
509in²
Step-by-step explanation:
Formula for calculating the area of a regular hexagon is given as:
A=(3√3a²)/2
'a' is one of the sides of the hexagon
Given a = 14in
Area = 3√3/2 × 14²
Area = 3√3/2 × 196
Area = 3√3 × 98
Area = 509.22in²
Area of the regular hexagon is approximately 509in²
Answer: You can use only common factor (3).
Step-by-step explanation:
12g²-27h²
3 . ( 4g² - 9h² )
Order of operations says you have to multiply first.
12 - 6 + x + 9
Now add/subtract, moving left to right
6 + x + 9
x + 15 is your answer :)
Add 10 to both sides
3x^2 = -5 + 10
Simplify -5 + 10 to 5
3x^2 = 5
Divide both sides by 3
x^2 = 5/3
Take the square root of both sides
x = √5/3
Simplify √5/3 to √5/3
<em>x = ±√5/3</em>
<u>Answer: A. x = ±√5/3</u>
