Could just be used as a variable.
Answer:
B 20r
Step-by-step explanation:
r² + + 100
r² = (r ) ( ) signs are all positive. 100 = (10) (10) last number. so
(r + 10)(r + 10)
r(r+ 10) + 10(r + 10)
r² + 10r + 10r + 100
r² + 20r + 100
y=1/2+4
y=2+4
y=6
or
y=1/2+4
y=1/6
y=6

Answer:
2(2n² + 2n) + 1
Step-by-step explanation:
(2n + 1)² can also written as
(2n + 1) × (2n + 1)
= 4n² + 2n + 2n + 1
= 4n² + 4n + 1
= 2(2n² + 2n) + 1
= an odd
