Answer:
8
Step-by-step explanation:
h=-3 , k=-2, x=5, y=-2
(x-h)^2+(y-k)^2 = r^2
(5-(-3))^2+(-2-(-2))^2
64+0=r^2
r=√64=8
hope this help Answer:( x - 3i√2)(x + 3i√2)
solve x² + 18 = 0
x² = - 18 ⇒ x = ±√- 18 = ±3i√2
factors are ( x - (3i√2))(x - (-3i√2))
x² + 18 = (x - 3i√2)(x + 3i√2

Answer:nice!
Step-by-step explanation:
Its 16x^2 i'll give explanation in a second
Area is 6000 yd2
LW = 6000
field must be 40 yards longer than its width
L = W + 40
Replace L with W+40 in 1st equation to solve for Width
(W+40)(W) = 6000
W2 + 40W - 6000 = 0
This is a quadratic but is factorable
Factors of -6000 that add to 40 are (100)(-60)
(W+100)(W-60) = 0
W = -100 or W = 60
Since the width will not be negative discard -100
The width is 60 yards
Length is W+40 = 100 yards
