Answer:
7, 4ft
Step-by-step explanation:
Given data
area = 108 square feet
length = (x-1)
width = (x-4)
Area=L*W
open bracket
a= 1
b=-5
c=-104
Applying the quadratic formula
x=-13
or
x=8
since x cannot be negative
x= 8
length = (x-1)= 8-1= 7ft
width = (x-4)= 8-4= 4ft
Answer:
Therefore,
The Equivalent expression is option A,
Step-by-step explanation:
Given:
Expressions is
To Find:
Equivalent expression ?
Solution:
We have Law of indices
For option A
(1.08^t)^4
Hence option A is the Equivalent expression.
For option B
1.08^8t/1.08^2t
Which is not the Equivalent expression.
For option C
1.08^4*1.08^t
Which is not the Equivalent expression.
For option D
1.08^6t/1.08^2t
Which is not the Equivalent expression.
Therefore,
The Equivalent expression is option A,
