Answer:
i think 11
Step-by-step explanation:
STEP 1
Equation at the end of step
((14 • (x2)) - 7xy) - (3•72y2)
Equation at the end of step 2
((2•7x2) - 7xy) - (3•72y2)
STEP 3
STEP 4
Pulling out like terms
4.1 Pull out like factors :
14x2 - 7xy - 147y2 = 7 • (2x2 - xy - 21y2)
Trying to factor a multi variable polynomial :
4.2 Factoring 2x2 - xy - 21y2
Try to factor this multi-variable trinomial using trial and error
Found a factorization : (2x - 7y)•(x + 3y)
Answer:
6-5
Step-by-step explanation:
It's very hard to work out on here, but your final answer is x=3.
You can substitute x=3 in for x to test it.
Hope this Helps!

Answer:
an = 5/2 +3/2(n -1)
Step-by-step explanation:
The common difference is ...
4 -5/2 = 3/2
The general rule is ...
an = a1 +d(n -1)
For a1 = 5/2 and d = 3/2, the rule for this sequence is ...
an = 5/2 +3/2(n -1)
___
This can be simplified to ...
an = 1 +3/2n
