So, we know the sum of the first 17 terms is -170, thus S₁₇ = -170, and we also know the first term is 2, well
well, since the 17th term is that much, let's check what "d" is then anyway,
It’s B
6x3=18
sqrt18 simplifies to sqrt9 x sqrt2
sqrt9 is 3 for 3sqrt2
Answer:
The strategies (2), (3) and (5) can be applied.
Step-by-step explanation:
In this case we need to compute the product of 629 × 100.
The product can be found in the following ways:
- multiplying (600 + 20 + 9) x 100
- putting 2 zeros on the end of 629
- multiplying (6,000 + 200 +90) x 10
Thus, the strategies (2), (3) and (5) can be applied.
Not similar, since the ratio of corespondent side is not constant
suppose ∆PRQ ~ ∆MRN, then RN/RP = RM/RQ but the reality contradict
