Answer:
A pentagon.
Step-by-step explanation:
A pentagon is a 5-sided polygon. Its interior angles each are equivalent to 108°.
108° ≥ 90°, so the angles are obtuse.
Therefore, a 2-D shape with 5 obtuse angles is a <u>pentagon</u>.
Answer:
1.4
Step-by-step explanation:
Answer:

The general solution is

Step-by-step explanation:
Given differential equation is
y''-4y'+4y=0
and 
To find the
we are applying the following formula,

The general form of equation is
y''+P(x)y'+Q(x)y=0
Comparing the general form of the differential equation to the given differential equation,
So, P(x)= - 4







The general solution is
