create an expression, to equal 13, using any grouping of addition, subtraction, multiplication, and division. you must use all the basic operations at least once (addition, subtraction, multiplication, and division) and you must use at least three sets of parentheses. you can use exponents if you want as well.

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
