In 9. and 10., estimate, and, the use a formula to find the perimeter

9, A square 22 in long on each side

10, A rectangle 13 ft long and 38 ft wide

In 9, the perimeter is 88 ft and in 10, the perimeter is 102 ft

Step-by-step explanation:

In question 9. The perimeter of a square can be given as

4 × length = 4L

If the square is 22 ft long, perimeter will be

4 × 22 = 88 ft

In question 10, the perimeter of a rectangle is given as 2length + 2width

That is 2(l + w)

If l is 13 ft and w is 38 ft, the perimeter is

2(13 + 38) = 2(51)

p = 102 ft

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.

x= 3^y
