Answer:
Step-by-step explanation:
formula for the volume of a hexagonal pyramid is (
/2)*
*h
where is is the side length, for this pyramid it's 4
and h is the height, for this pyramid it's 12
(/2)*
*12 = 96*
the correct answer for this is the last choice:
It is incorrect because the length of the unknown side is the square root of 7,225.
Answer:
x=-2 and x = 5
Step-by-step explanation:
The solutions to the equation are where the graph crosses the x axis
We can see that the graph crosses at x=-2 and x = 5
Answer:
Step 3 they took the square root incorrectly
Step-by-step explanation:
5 ( x-2)^2 +6 = 86
Subtract 6 from each side
5 ( x-2)^2 +6 -6= 86-6
5 ( x-2)^2 = 80
Divide each side by 5
5 ( x-2)^2 /5 = 80/5
(x-2)^2 = 16
Take the square root of each side
sqrt((x-2)^2) = ±sqrt(16)
x-2 = ±4
