Answer:
1350
units²
Step-by-step explanation:
The regular hexagon consists of 6 equiangular triangles
The area (A) of a equilateral triangle is calculated as
A =
( s is the side length )
Here s = 30 , then
A =
=
= 225
units²
Thus the area of the regular hexagon is
area = 6 × 225![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
= 1350
units² ← exact value
≈ 2338.3 units² ( to 1 dec. place )
Answer:
30 liters
Step-by-step explanation:
To me it's kind of like multiplying and dividing.
So, what I did was 30,000 divided by 30 and got 1,000.
1,000 x 30 = 30,000.
That's what I did. You probably have your own way of doing it, but the answer is 30. I'm sorry if my explanation isn't good enough but I tried. Thanks for the question and enjoy your answer :)
One approach is to isolate y in the bottom formula, then fill it in to the top one:
x-y=-3 => y = 3+x
so substitute 3+x for y in the top formula (watch the signs) and simplify
x² - 3 - x = 3 => x² -x -6 = 0 => (x+2)(x-3)=0
so x=-2 or x=3.
for x=-2, y=1
for x=3, y=6
These are the solutions.
