I=k/d^2
4=k/d^2 and 1=k/64 so if we divide the first by the second we get:
4/1=(k/d^2)/(k/64)
4=(k/d^2)*(64/k)
4=64/d^2
d^2=64/4
d^2=16
d=4 meters
Answer:
B.

Answer:
(36) (x+6) (-10 or -2) i got this right on (ed)
Step-by-step explanation:
1 Add to both sides of the equation. The value of in this equation is 36.
2 Write the left side of the equation as a binomial squared. The left side of the equation becomes (x +6)2.
3 Use the square root property of equality.
4 Isolate the variable: x = -10 or -2
