Answer: 24 km2
Step-by-step explanation: Surface area is measured by multiplying two lengths. For example: The area of a square with sides of length a is Area = a * a = a²
Therefore, the answer is 24 km2

Therefore, function notation is a way in which a function can be represented using symbols and signs. Function notation is a simpler method of describing a function without a lengthy written explanation. The most frequently used function notation is f(x) which is read as “f” of “x”.
Answer:
y = 5x - 8
Step-by-step explanation:
Here. we want to find the equation of the line
The general form is;
y = mx + b
where m is the slope and b is the y—intercept
To get the slope, we can pick any two points on the line
These are;
(2,2) and: (3,7)
we have the slope as follows;
m = (y2-y1)/)x2-x1) = (7-2)/3-2) = 5/1 =5
So we have;
y = 5x + b
To get b , use any point on the line and substitute its coordinates
using (3,7)
7 = 5(3) + b
7 = 15 + b
b = 7-15
b = -8
So the equation of the line is (
y = 5x - 8
Answer:
Matt made the error
