ANSWER
EXPLANATION
We want to find the constant that must be added to
to form a perfect square.
Comparing the given expression to
we have
a=1 , b=-3 , and c=0.
We need to add
We substitute the values to get,
We change this to mix numbers to get,
The last choice is correct.
Answer: B
Step-by-step explanation:
Let's solve the given equation. Then we can see which other equation has the same answer.
-5n+31=-14n-5
36=-9n
n=-4
We need to fina another equation that gives n=4 as the answer.
A. Incorrect
3-6n+3n=-3+4-4n
3-3n=1-4n
n=-2
B. Correct
C. Incorrect
1=0.75n+3.25
-2.25=0.75n
n=-3
D. Incorrect
-1-22n=-20n-9
8=2n
n=4
The shape of the resulting cross section of the hexagonal pyramid in the diagram given is: a hexagon.
<h3>What is Hexagonal Pyramid?</h3>A hexagonal pyramid is a pyramid with six lateral faces and an hexagonal base.
