The differnce of 2 perfect cubes
remember
a³-b³=(a-b)(a²+ab+b²)
so
a polygon with seven sides is called a heptagon
FGHI
Step-by-step explanation:
The square FGHI needs to be created into a reflection for true congruence of the figure thus transformed across the axis.
FGHI's co-ordinates' signs are to be reversed for reflection thus coordinates:
2,-5
4,-5
2,-7
4,-7
are made into
-2,5
-4,5
-2,7
-4,7
Answer:
275 - 11=264
