Answer:
49n² - 70n + 25
Step-by-step explanation:
Area of a square = s²
Where,
s = side length = 7n - 5
Area of the square = (7n - 5)²
= (7n - 5)(7n - 5)
= 7n(7n - 5) -5(7n - 5)
= 49n² - 35n - 35n + 25 (distributive property of equality)
Add like terms
Area = 49n² - 70n + 25

Answer:
4
Step-by-step explanation:
Recall a linear function, is a line on a graph made up of an infinite amount of points which satisfy the relationship. That means at x=3 there is a specific point on the line with an output. The value of a function at x=3 asks, what is the output y value for the input x value?
To find it, we locate 3 on the x-axis. We draw a vertical line directly to the line following the grid line. We mark the point on the line. We then draw a horizontal line directly to the y-axis following the grid line. The point we hit on the y-axis is the value of the function.
Here it is 4.
