Chiyoko wants to fence off a section of her backyard to be an exercise space for her dogs, as shown in the diagram. Chiyoko must find the perimeter to figure out how much fencing she needs. How can Chiyoko express the perimeter in the most simplified way? A.4(x + 4)

B. x(x + 4)

C. 5x + 4

D . 5x + 8

It is D

Step-by-step explanation:

The way to find the perimeter is to add the side lengths and then simplify by combining like terms.

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.

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.
