The area of the rectangle is 18 , I didn't understand the equation fully so I did (4*4.5=18) because (1/2=.5) .
Hope this helps
Answer:
Step-by-step explanation:
Given expression:
Let u = (x - y):
To factor a quadratic in the form 
find two numbers that multiply to 
and sum to 
:
Therefore, the numbers are: -6 and -4.
Rewrite as the sum of these two numbers:
Factor the first two terms and the last two terms separately:
Factor out the common term (u - 2):
Substitute back in u = (x - y):
Simplify:
There is 525600 minutes in a year and 1063953 drinks, so 525600 and 1063953 divided is about 3
Y = 25x - 5 is the equation.
Answer:
Octagon
Step-by-step explanation:
Sum of interior angles = 3*360 = 1080
sum of interior angles, is also, s = (n-2)180
From that,
n-2)180 = 1080
n-2 = 1080/180
n = 6 + 2
n = 8
Therefore, the figure is an 8 sided polygon or an octagon
