Vertex form is basically commplete the square
y=a(x-h)^2+k
y=x^2+14x+4
take 1/2 of 14 and square it, (7^2=49)
add that and its negative to right side
y=x^2+14x+49-49+4
factor perfect squaer
y=(x+7)^2-49+4
y=(x+7)^2-45
answer is A
Z^5/8
You can tell this because exponents get added together when multiplying and the fact that the fraction goes down by a multiple of 1/8.

Answer:

Step-by-step explanation:
we can easily calculate the perimeter of three points, using vectors. See the picture...
Step-by-step explanation:
Let's solve for c.
5c=d
Step 1: Divide both sides by 5.
5c
5
=
d
5
c=
