Answer:
x = ±2sqrt(15)
Step-by-step explanation:
x^2 = 60
Take the square root of each side
sqrt(x^2) = ±sqrt(60)
x = ±sqrt(60)
x = ±sqrt(4 *15)
x = ±2sqrt(15)
Answer: the answer is c
Step-by-step explanation:
your welcome
Step-by-step explanation:
The awnser is -6+6 because it would end up being 0, which is not positive nor negative
I'm assuming it's 10^6, so 10 would be the base, and 6 would be the exponent.
Firstly, we need to draw triangle
we know that
O is a centroid
and centroid divides median into 2:1
so,

we have FO=4
so, we can plug it


now, we can find CF
CF=OC+FO
CF=8+4
CF=12
now, we can see triangle ACF is a right angled triangle
so, we can use pythagoras theorem

now, we can solve for x



Since, it is equilateral triangle
so,

we know that
E is a mid-point
so,

now, we can plug values
