Perfect squares are rational numbers multiplied by themselves. Here are the perfect squares between 25 and 100:
5*5=25
6*6=36
7*7=49
8*8=64
9*9=81
10*10=100
Hope this helps :)
Answer:
The general solution is

+ 
Step-by-step explanation:
Step :1:-
Given differential equation y(4) − 2y''' + y'' = e^x + 1
The differential operator form of the given differential equation
comparing f(D)y = e^ x+1
The auxiliary equation (A.E) f(m) = 0




The roots are m=0,0 and m =1,1
complementary function is 
<u>Step 2</u>:-
The particular equation is 
P.I = 
P.I = 
P.I = 



applying in integration u v formula

= 





again integration 
The general solution is 

+ 
Answer:
75
Step-by-step explanation:
180-30=150
150/2=75
C is the correct answer. using the equation (y-y1)=m(x-x1)
Answer:
SAS theorem
Step-by-step explanation:
If
and m∠ECD = m∠BCA, then the triangles are similar by the SAS theorem.

So,
and m∠ECD = m∠BCA because vertical angles are congruent
Therefore ΔECD is similar to ΔBCA by SAS theorem
