Answer:
The base and height of the garden are 4.60 ft and 5.60 ft.
Step-by-step explanation:
The area of the garden is, <em>A</em> = 24 ft².
The base height of the garden are:
base (<em>b</em>) = 6x - 4
height (<em>h</em>) = x + 3
Compute the value of <em>x</em> as follows:

The last equation is a quadratic equation.
Compute the roots of the quadratic equation as follows:

The value of base and height are:

Thus, the base and height of the garden are 4.60 ft and 5.60 ft.
The numbers are constants, and the multiplication symbol is an operator.
If this equation were 4x * 6 = 24, then 4 would be a coefficient and x would be a variable. 6 and 24 are still constants and the multiplication symbol is still an operator.
Given:
The expression is

To find:
The error in Frankie's work.
Solution:
We need to simplify
, so


and,


Now,





Therefore, there is error in Frankie's last step. In that step, he did not subtract the mixed fraction correctly.
Answer: B. Between 150 and 200
