Answer:
Length = 30m and Breadth = 10m
Step-by-step explanation:
Given that :
Perimeter = 80 m ;
Breadth = 1/3 of Length ; Length = l
We know that :
Perimeter of rectangle = 2 ( L + B ).
80 = 2 ( L + 1/3 L )
80/2 = 4/3 L.
40 = 4/3 L
3/4 × 40 = L.
3 × 10 = L.
L = 30m.
Breadth = 1/3 of Length.
Breadth = 1/3 × 30.
Breadth = 10m.
Step-by-step explanation:






The function f(x) - g(x) is an illustration of a composite function
Leanne's end result of f(x) - g(x) = -1/2x + 9 is correct
<h3>How to estimate the student's answer?</h3>
The functions are given as:
f(x) = 1/2x + 6
g(x) = x - 3
The function f(x) - g(x) is calculated using:
f(x) - g(x) = 1/2x + 6 - x + 3
Collect like terms
f(x) - g(x) = 1/2x - x + 6 + 3
Evaluate the like terms
f(x) - g(x) = -1/2x + 9
By comparing the above solution to the students' response, we can see that:
Leanne's end result of f(x) - g(x) = -1/2x + 9 is correct
