I do not believe so but dont quote me on it.
Answer:
100 i think if its a square its 100
Step-by-step explanation:
2040 = n/2(20+(n-1)4)
4080 = n(20+4n-4)
4080= 20n +4n^2 -4n
1020 = 4n + n^2
n^2 +4n -1020 =0
use common formula (can't write out so just look at answers. sorry)
which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge
Answer:
119
Step-by-step explanation:
Since the terms have a common difference (d) between consecutive terms then the terms are an arithmetic sequence with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
a₁ = 2 and d = 20 - 11 = 11 - 2 = 9, hence
= 2 + (13 × 9) = 2 + 117 = 119
Answer:
For number 1, it's 3(x^2+1)
Step-by-step explanation:
Step 1: Identify the GCF of the polynomial.
Step 2: Divide the GCF out of every term of the polynomial.
