Answer:
The similarities are
1) The length of E and F can be described by two parallel lines spaced 3 blocks apart where the parallel line on the left of both E and F is 2 blocks long, while the parallel line on the right is one block long
2) Both height of E and F can be described by two parallel lines spaced 2 blocks apart where the parallel line on the top of both E and F is 3 blocks long, while the parallel line at the bottom is one block long
3) The interior of E an F can be described by parallel lines 2 blocks long in the horizontal portion and one block long in the vertical portion
The differences are
1) The difference between E and F is that the parallel lines used for the construction of E are all one block higher than that of F
2) The other difference is that all the lines used for the construction of the figure E are 3 blocks to the left of those used for the construction of F
Figure F is essentially the translation of figure E three blocks to right and one block down
Step-by-step explanation:
1) Cancel out the common factor which in this case is 8 
2)First apply exponent rule 
now cancel out the common factors which are n and n+7 leaving you with 
3)Factorize 
cancel out the common factor in this case x+2 leaving you with 
4) Factorize 
cancel out the common factor in this case 3w-1 leaving you with

Answer:
- 5, 2, 9, 16 and d = + 7
Step-by-step explanation:
to obtain the first four terms substitute n = 2, 3, 4 into the recursive formula
f(1) = - 5 ← given
f(2) = f(1) + 7 = - 5 + 7 = 2
f(3) = f(2) + 7 = 2 + 7 = 9
f(4) = f(3) + 7 = 9 + 7 = 16
common difference d = 16 - 9 = 9 - 2 = 2 - (- 5) = 7
