The perimeter of a rectangle is 48 cm. The length is 12 cm longer than the width. What are the length and width of the rectangle?
Length: 18 cm; width: 6 cm
Ogth: 12 cm; width: 6 cm
Length: 24 cm; width: 12 cm
Length: 23 cm; width: 11 cm

Length: 18cm

Width: 6cm

Step-by-step explanation:

1. make sure that the length in the width are 12 cm apart. that leaves options a, c, and d.

2. multiply the length by 2 and the width by 2 and then add those two answers together. if it equals 48 then that is the right answer.

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.
