Answer:
The common difference is 1.5
Use the explicit formula to find a1.
a1 = 1.2
What is the explicit formula for the arithmetic sequence?
= 1.2 + (n - 1)1.5
Step-by-step explanation:
Answer:
width=x
length=5x
area= 300ft2
area=lxb
300=5x(x)
300=5x^2
x^2=60
x=7.74
7.74(5)=38.7
dimensions are 38.7ft by 7.74 ft
