Copy and insert two pairs of brackets to make the equation true. 1 + 2 x 3 + 4 x 5 +6 x 7+ 8 x 9 = 505

Answer and explanation:

1For BODMAS to apply to the equation and five us the correct result of 505, we did have to place the brackets where they should be and show the order of operations using the BODM

1 + 2 x 3 + 4 x 5 +6 x 7+ 8 x 9 = 505

1+(2

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.
