Answer:
If you solve for a2+b2=c2 you will see
Step-by-step explanation:
1 will be 11.61
2. Will be 7.6
so there will be a 4.01 difference
1. a2+3(2)=12(2)
a2+9=144
then subtract 9 from 144
you get 135
then
135

Answer:
(2x - 7)³ ≠ (2x)³- 7³
Step-by-step explanation:
(2x - 7)³= (2x)³- 7³
Use pascal's triangle to expand left side. Simplify all else.
(2x)³ + 3(2x)²(-7)¹ + 3(2x)¹(-7)² + (-7)³ = 8x³- 343
8x³ + 3(4x²)(-7) + 3(2x)(49) + (-7)³ = 8x³- 343
8x³ - 84x² + 294x - 343 = 8x³- 343
