Answer:
A / D / E
Step-by-step explanation:
f (1) = 1
f(2) = 5
f(3) = 9
The 12th term of the geometric sequence would be -8,388,608.
Step-by-step explanation:
Given that,
The first term of geometric sequence is = a1 = 2
a2 = -8
a3 = 32
Now, the formula for nth term of a geometric sequence is 
So,


Now,
a = 2
a*r = -8
By putting the value of a, we get
2*r = -8
or
r = -4
For 12th term, the formula would be:

now, put the values of a and r:

a12 = 2 * (-4,194,304)
a12 = -8,388,608
Hence, the 12th term of the geometric sequence would be -8,388,608.
The answer should be 15x + 10y ≤ 120
Since the pizza is x and chicken fingers is y then this should be the answer.
I would explain more but you only have five minutes left :)

Kindly check explanation
Step-by-step explanation:
Given the dimension of the dog pen = 30 ft by 40 ft.
Using the knowledge of geometry, that know that a rectangle has been built, the area of the pen should be :
Area of rectangle = Length * width
Area = 40 * 30
Area = 1200 ft²
Perimeter of rectangle = 2(Length + width)
Perimeter = 2(40 + 30)
Perimeter = 2(70)
Perimeter = 140 feets
Hence, area of the pen should be 1200 ft² and its perimeter or fencing should measure 140 feets
The answer in simplified form is {5x^2+1}{2x+1}
