Which shows the correct substitution of the values a, b, and c from the equation 2 *+ ? - 4 into the quadratic formula?
Quadratic formula: x
-0.40
2 a
Ox-(-1):V-1)-4(1)(-4)
2(1)
-11V1?-4-1)(-4)
2(-1)
- 1 + a)? -46-12-2)
21-1)
x --(-1)/(-1). - 4(1)( - 2)
2(1)

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

um is there supposed to be a picture?
