Answer:
y = 0
Step-by-step explanation:
- 2y - 4 = 4 (y - 1)
- 2y - 4 = 4y - 4
- 2y - 4y = - 4 + 4
- 6y = 0
- y = 0/6
- y = 0
y = 0
A net is just a 3D shape made into a 2D shape. So when you have a net, it is easier to make sure you count up all the sides without missing one or counting one twice.
Answer:
B
Step-by-step explanation:
They help support the tree in shallow soil so it does not fall over
A polynomial function of least degree with integral coefficients that has the
given zeros 
Given
Given zeros are 3i, -1 and 0
complex zeros occurs in pairs. 3i is one of the zero
-3i is the other zero
So zeros are 3i, -3i, 0 and -1
Now we write the zeros in factor form
If 'a' is a zero then (x-a) is a factor
the factor form of given zeros

Now we multiply it to get the polynomial
