Answer:
A. The 2 groups could be quadrilateral and triangles.
quadrilateral-1,2,,6,7
Triangles-3,4,5,8,9
B.You could also sort them into shapes with 4 sides and shapes with 3 sides.
4 sides-1,2,,6,7
3 sides--3,4,5,8,9
C. They are all polygons becuase they all have 3 or more striaght sides and they all are closed shapes.

<em>x=45degrees</em></h3>
<h2>
Step-by-step explanation:</h2>
Let the angle to be solved be x
Let the supplement/compliment by y
x+y=90 Complimentary angles add up to 90 degrees.
x+3y=180 Supplementary angles add up to 180 degrees, the other angle is thrice the other compliment.
Evaluating this as a system:
x+y=90 Isolate x:
x=90−y Input into the other equation:
(90−y)+3y=180 Combine like terms, isolate y and its coefficients:
2y=90 Isolate y
y=45 Input into the first equation:
x+45=90 Isolate x:
x=45degrees

Answer:
FV= $70,887.15
Step-by-step explanation:
<u>First, we need to calculate the future value of the $130 deposit for 5 years:</u>
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit= $130
i= 0.08/12= 0.0067
n= 5*12= 60 months
FV= {130*[(1.0067^60) - 1]} / 0.0067
FV= $9,561.96
<u>Now, using the following formula, the future value of the investment after 25 years:</u>
<u />
FV= PV*(1 + i)^n
n= 25*12= 300
FV= 9,561.96*(1.0067^300)
FV= $70,887.15
