Answer:
jk
Step-by-step explanation:lol
0.45 as a fraction is
45/100 and in simplest form it is
9/20.
Option B:
is sufficient to prove that
ll 
Explanation:
Given that ACD is a triangle.
The line EB intersects the sides AC and AD of the triangle.
The point E intersect the side AD and B intersect the side AC.
We need to prove that
ll 
Then, the side splitter theorem states that "If a line intersects two sides of a triangle and divides the sides proportionally, the line is parallel to the third side of the triangle".
From the side splitter theorem, the line EB intersects the two sides of the triangle AC and AD and divides the sides proportionally.
Thus, the proportion of the sides is given by

This proportionality shows that the line is parallel to the third side of the triangle.
Hence,
is sufficient to prove that
ll 
Therefore, Option B is the correct answer.
Answer:
The answer to your question is x = 4d/t - S1
Step-by-step explanation:
Data
total time = t = 2.75 hours
Initial speed = S1 = 55 mi/h
Final speed = x
distance = d = 60 mi
Formula
speed = distance / time
Average speed = (Initial speed + final speed)/2 or
= (S1 + x)/2
Substitution
(S1 + x)/2 = 2(d) / t
Solve for x
x = (2d/t)2 - S1
Simplification and result
x = 4d/t - S1
Answer:
744
Step-by-step explanation:
12a^2 + 4b
Plug-in:
12(8)^2 + 4(-6)
12(64) + 4(-6)
768 - 24
