Answer:
x = 6
Step-by-step explanation:
5 sides all the same length
s = 22.5/5
s = 4.5
--------------------
x - 1.5 = 4.5
Add 1.5 to both sides
x = 6
Answer:
this should be right if not comment and I'll relook it.
FOIL Method.
You will get the same answer x^2+ 7x- 18
Answer:
(-4,1)
Step-by-step explanation:
The given parabola is
When we rewrite in vertex form, we get;
Or
When we compare to:
We have 4p=-4
This means p=-1
But the vertex is at:
(-4,2)
Since it is a vertical parabola that opens down, the focus is one unit(|p|=1) below the vertex.
Hence the focus is (-4,1)
Answer:
Step-by-step explanation:
Given that the left angle =
The right angle across from it
The other two angles are x and x.
We know that the sum of angles at a point equals 360 degrees.
Therefore,
The value of x is approximately 38.5 degrees.
