Step-by-step explanation:
correct but what's the question
Less. The distance across the field is less than 20 km
Answer:
The value of n is 1
Step-by-step explanation:
Given the expression 
In other to solve for n we have to perform a series of step wise operations as follows
collecting like terms we have


The negative signs will council out on both sides we have

Dividing both sides by 2 we have
n= 

Answer
Option C is correct.
Explanation
We are told that the equation of a straight line is
y = 3x + 9
We are then told that if the 9 is replaced with a 3, what does this indicate?
When graphs are shifted upwards or downwards along the y-axis, the effect of this translation is shown in the new equation for the graph.
If a graph, y = f(x) is moved a units upwards on the y-axis, the new graph has an equation of y = f(x) + a
If a graph, y = f(x) is moved b units downwards on the y-axis, the new graph has an equation of y = f(x) - b
So, when a graph of y = 3x + 9 changes to y = 3x + 3, it indicates that 6 units have been subtracted from the original function; showing that the original function has been moved 6 units downwards.
Hope this Helps!!!
Answer:
The difference in area between the trapezoid and the rectangle is 10 in²
Step-by-step explanation:
The dimensions of the trapezoid are given as follows;
Base 1, a = 12 in
Base 2, b = 10 in
Height, h = 10 in
Area, A of trapezoid;

The dimensions of the rectangle are given as follows;
Base = 12 in
Height = 10 in
Area, A of rectangle;
Base × Height = 12 × 10 = 120 in^2
Therefore, the difference in area between the two packages is found as follows;
Difference in area between trapezoid and rectangle = 120 - 110 = 10 in²
The difference in area between the trapezoid and the rectangle = 10 in².
