An = a1 * r^(n-1)
n = term to find = 18
a1 = first term = 3
r = common ratio = 4/3
now we sub
a18 = 3 * 4/3^(18 - 1)
a18 = 3 * 4/3^17
a18 = 3 * 133
a18 = 399
Answer:
Step-by-step explanation:
its the first one in edge
Answer:
1
Step-by-step explanation:
Start at -0.5 and go toward 0.5.
From -0.5 to zero, it's a distance of 0.5.
From zero to 0.5, it's also a distance of 0.5.
Add the two distances, 0.5 + 0.5 = 1.
The distance between -0.5 to 0.5 is 1.
Move the 14 over and get
5x = 2
divide by 5
x = 2/5
Answer:
(3)(x+7)(x-1)
Step-by-step explanation:
3x^2+18x-21
Let's start by taking 3 out of the equation.
3(x^2+6x-7)
Now, when we factor, we need to find two numbers that add up to 6 and multiply to -7.
The numbers would be 7 and -1.
So the factored form of this would be:
(3)(x+7)(x-1)
