Answer:

32 feet of fence

Step-by-step explanation:

The garden is a square, so the length and width are equal.

A = L x W

W = L

A = W²

A = 64

W² = 64

W = √64 = ±8 -- (-8) would be extraneous

W = 8 ft

L = 8ft

Since she is putting the fence around the garden, she needs to find the perimeter.

P = 2L + 2W

P = 2(8) + 2(8)

P = 16 + 16

P = 32 ft

32 feet of fence

(15)Simplify the expression below. Show your work -(-7y+12)
kotykmax [81]
15. -(-7y + 12) = 7y - 12

16. 1/a = 16/18
      cross multiply
      16a = 18
      a = 18/16 = 9/8

17. 8x - 12 = 4x + 24
      8x - 4x = 24 + 12
      4x = 36
      x = 36/4
      x = 9

18. -6b > 42           4b > -4
       b < 42/-6          b > -4/4
       b < - 7              b > -1
so b < -7 and b > -1

19. 6 more then the product of 8 and n
      6 + 8n

20. 45 = 3b + 69
      45 - 69 = 3b
      -24 = 3b
      -24/3 = b
      -8 = b

Geometry IXL please help !
elena-s [515]

Answer:

The answer to your question is 10 in

Step-by-step explanation:

Data

Circumference = 20π in

Diameter = ?

Formula

Circumference = 2πr

Process

1.- Equal the formula to the value

                     2πr = 20π

2.- Solve for r

                        r = 20π/2π

3.- Simplification

                       r = 10/2

4.- Find the diameter

           diameter = 2r

           diameter = 2(10/2)

           diameter = 10 in

I have no idea how to solve this. Help would me much appreciated.
Otrada [13]

Answer:

Adam is 9 years old.

Step-by-step explanation:

Let d and c represent Adam's and Alicia's ages.

d = c - 15, and

c + 6 = 2(d + 6)

Rearrange d = c - 15 as c = d + 15, and then substitute d + 15 for c in the second equation.  We obtain:

d + 15 + 6 = 2(d + 6), or

d + 21 = 2d + 12

Combining like terms, we get 21 = d + 12, or 9 = d.

If d = 9 then c = d + 15, or c = 9 + 15, or c = 24.

Adam is 9 years old.
