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
To put a fraction into simplest form, you need to divide both the numerator and the denominator by the GCF of both of these numbers.
35 and 42 have a GCF of 7.
So, if we divide
35/7=5
42/7=6
Therefore, 35/42 in simplest form is 5/6
4 = 2/4u
Multiply both sides by 4u
16u = 2
Divide both sides by 16, and simplify.
u = 1/8

Answer:
the range is {-2, 6, 22}
Step-by-step explanation:
Use " ^ " to indicate exponentiation: f(x) = x^2 - 3.
For each value in the domain {1, 3, 5}, calculate f(x) = x^2 - 3:
f(1) = 1^2 - 3 = -2
f(3) = 3^2 - 3 = 9 - 3 = 6
f(5) = 5^2 - 3 = 25 - 3 = 22
Thus, the range is {-2, 6, 22}
