Answer:
D
Step-by-step explanation:
l = a * r ^ (n - 1)
n = 11

r = 2
L = 1 * 2^(11 - 1)
L = 2^ 10
L = 1024
When you solve a proportion, your first step should be to cross-multiply.

=

When you cross-multiply, you should get this equation:
(2x)(3) = (x + 3)(5)
Now, solve it using algebra.
(2x)(3) = (x + 3)(5) Multiply
6x = 5x + 15 Subtract 5x from both sides
x = 15
The value of
x is 15.
