The answer is A
its a simple eqaution carry the 1 over
Answer:
i cant see
Step-by-step explanation:
We can solve this problem using discriminant.
x^2-4x-12's discriminant is
(-4)^2-4*-12=16+48 which is clearly larger than 0
This means that it crosses over the axes 2 times.
In case you don't know what discriminant is, its in equation ax^2+bx+c
the discriminant is b^2-4ac.
If its positive it has 2 crosses with x axis, if negative then 0 crosses, if 0 then 1 cross.
Hope this helped at least a little bit :D
79,350 cm
Explanation:
115x115=13,225 (this is the area of one side)
13,225x6=79,350(a cube has 6 sides)
4x=112
x=112/4 ( '/' means divide)
x=28
