Evaluate the expression 6^2 + x-x^2 for x=3

30

Step-by-step explanation:

Given the following mathematical expression;

6² + x - x²

When x = 3

Thus, we would substitute the value of "x" into the expression;

36 + 3 - (3)²

Applying BODMAS (Bracket of Division, Multiplication, Addition and Subtraction).

36 + 3 - 9

39 - 9

30.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
