Which statement shows the following conditional statement written as a biconditional? "If a triangle is scalene, then the triangle has no congruent sides."

If a triangle has no congruent sides, then the triangle is not scalene.
A triangle is scalene if and only if it has no congruent sides.
A triangle is equilateral if and only if it is not scalene.
If a triangle has some congruent sides, then the triangle is not scalene.

you can't solve x because it is 2 linear equation and you only have one equation

answer: 414,377,008

step-by-step explanation:

just multiply it

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
