The formula for the sum of n terms in an arithmetic progression is:
S = n/2 * (2a + (n-1)d)
Here, the common difference, d, is 8 and the first term, a, is 1. Substituting these into the formula, we get:
S = n/2 * (2*1 + 8(n - 1))
S = n + 4n² - 4n
S = 4n² - 3n
The answer is A.
Answer:
w = - 15
Step-by-step explanation:
Assuming you mean
= - 4 ( multiply both sides by 3 to clear the fraction )
w + 3 = - 12 ( subtract 3 from both sides )
w = - 15
⟘ = 90°
The intersect point is at the N not P, so the answer is m∠BNP = 90°
Answer:
50.264 grams -> 50.2
Step-by-step explanation:
U want to go x2 plus x so its x3 then 4x3times -15 so x=3.33333
