We define variables:
x = represent the width of the field
y = represent the length of the field
We write the perimeter (with no fencing along the river):
2400 = 2x + y
We clear y:
y = 2400-2x
Answer:
an expression for the length of the field as a function of x is:
y = 2400-2x
4/(1+3) or
Addition is the first step for two reasons.
1) the Order of Operations requires you do operations in parentheses first
2) the division cannot be performed until you know what you're dividing

Answer:
12288
Step-by-step explanation:
its a geometric sequence where each term is 4 x the term before it
so the 7th term = 3 *4^6 = 12288
