Answer:
25
Step-by-step explanation:
We require to solve for n, hence
n(n + 1) = 325
multiply both sides by 2 to eliminate the fraction
n(n + 1) = 650
n² + n = 650
subtract 650 from both sides to have equation in standard form
n² + n - 650 = 0 ← in standard form
(n + 26)(n - 25) = 0 ← in factored form
equate each factor to zero and solve for n
n + 26 = 0 ⇒ n = - 26
n - 25 = 0 ⇒ n = 25
however, n > 0 ⇒ n = 25
Answer:
s =
Step-by-step explanation:
Given
v² = u² + 2as ( subtract u² from both sides )
v² - u² = 2as ( divide both sides by 2a )
= s
Given
v² = u² + 2as ( subtract 2as from both sides )
v² - 2as = u² ( take the square root of both sides )
± = u
