Answer:
B. x=2
Step-by-step explanation:
The formula to find the axis of symmetry is -b/2a.
So, in this case, we find our b and a, which are 3 and -12.
Plug them into the formula.
-(-12)/2(3)
The negative sign times another negative makes it into a positive, now we have a positive 12 and then 2 multiplied by 3 equals 6.
Our new equation is 12/6.
Then, simply solve it, 12 divided by 6 equals 2.
Therefore, B would be your answer, x=2.

Answer:
this triangle is ABC with A(-2 ; -3), B(4; - 3) and C(3;5)
=>
using Heron theorem, we have:
with S is the area of the triangle
Step-by-step explanation:
The equation to find the volume of a sphere is V=4/3(pi)r^3.
So I cubed 12, times by 4, and divided by 3, so the volume of the beach ball is 2,304(pi) cubic inches. Hope this helps.
Well when you do a percent you wanna set up a proportion. Part over total and then percent over 100. I’m not sure if this helped but this is my advice. Remember the part over total, you might have to search for it, but when you set that up just multiply and divide and you got it!! Hope this helped (:
