Answer:
B
Step-by-step explanation:
Flipping a graph keeps the figures size the same, so it isn't A. Flipping it doesn't rotate the angles either(R is equal to R', S to S' etc.), so the answer is B.
Since we know that
(a+b)
2
=a
+2ab+b
(a−b)
−2ab+b
Now,
(i)
(x+3y)
=x
+2×x×3y+(3y)
+6xy+9y
(ii)
(2x−5y)
=(2x)
−2×2x×5y+(5y)
=4x
−20xy+25y
(iii)
(a+
5a
1
)
+2×a×
2a
+(
+1+
4a
(iv)
(2a−1a)=(1a)
(1a)
=1a
Answer
first get their difference and then get positions of the difference and get the factors and then you will get the nth term
Yes
21 it is the fifth number
