I assume O is where the three medians meet.
because triangle ABC is equilateral, the median is also the angle bisector and the altitude.
BO is 2/3 of BE, BE=CF=AD=20, so BO=40/3
Answer:
Ok so 1. I am in AP Calculus BC and I legit just fully learned how to do exponents (I had a rough year in algebra 1 lol) so don't feel bad. And 2. It's really simple. When you multiply exponents you so just add them so x^2 * x^3=x^5. This makes sense visually since x^3 is x*x*x and x^2 is x*x and when you multiply that out you get x*x*x*x*x. Division is also pretty simple and all you have to do is subtract them. (There is a reason for this but its not important but I'll explain it anyways. Basically when you divide it is the same thing as multiplying by a negative exponent so x^3 / x^2 = x.) When you have multiple variables all you have to do is combine like terms so if you have something like xy^2*xy^4 you would get (x^2)(y^6). As for your problems, here:
8vx
63ce
21a^2
48xw^2
30m^3n^2
120a^2c^2x^3
2n
8x
3wx
4ac^2
2wx^2
2a^2c
5a
3
4c
8ab
7bc
8ac
I hope this helps!
(Also, double check those when you put them in please lol)
Answer:
12
Step-by-step explanation:
The equation is:
1/2x+4x+6-1/2x-2
Ok so you can cancel out 1/2x and 1/2x because 1/2x-1/2x=0
You are left with:
4x+4
If you plug in 2 for x
4(2)+4=12
I hope this helps :)
A zero is in the hundredths place so we do not need to change the number in the tenths place. The answer is 32.6 If the hundredths place had a 6,7,8, or 9 than you would round to the nearest tenths place, so if you had 32.68 than you would round it to 32.7
