Answer:
h = 13 units²
Step-by-step explanation:
The way to find the area of a parallelogram is to multiply the length of one side (21) and multiply it by the height:
A = l*h
We know the area and the length:
273 = 21*h
Now we solve for height.
273/21 = (21*h)/21
273/21 = h
273/21 = 13
h = 13 units²

Explanation:
If y varies inversely as x, the two variables can be represented in an equation in the form
y
=
k
x
where
k
is some constant.
We are given that
y
=
5
when
x
=
6
. We can plug this into the above equation to find what
k
is:
5
=
k
6
30
=
k
Based on this we can create our equation:
y
=
30
x
And then find
x
when
y
=
2
:
2
=
30
x
2
x
=
30
x
=
15
Answer: Im pretty sure the answer is -14

Answer:
The zeros of the given polynomial function f(x) are -3,0,-4
Step-by-step explanation:
Given polynomial is 
To find the zeros of the given polynomial:
First equate the polynomial function f(x) to zero
That is 
By synthetic division we can solve it
-3_| 3 21 36 0
0 -9 -36 0
_____________________
3 12 0 0
Therefore x+3 is a factor
That is x=-3 is a zero
3x=0 or x+4=0
Therefore x=0 or x=-4
Therefore the zeros are -3,0,-4
