What is the approximate circumference of a circle with a diameter of 500 kilometers ? use pi= 3.14.

1 answer:

7 0

The formula for a circumference is L=pi*diameter
So you have to replace d for 500:
L=circumference= 3.14*500 = 1570 kilometers, so answer is "b"

Solve for x in the equation x^2+10x+12=36.

Alexandra [31]

Solve for x:
x^2 + 10 x + 12 = 36

36 = 36:
x^2 + 10 x + 12 = 36

Subtract 12 from both sides:
x^2 + 10 x = 24

Add 25 to both sides:
x^2 + 10 x + 25 = 49

Write the left hand side as a square:
(x + 5)^2 = 49

Take the square root of both sides:
x + 5 = 7 or x + 5 = -7

Subtract 5 from both sides:
x = 2 or x + 5 = -7

Subtract 5 from both sides:
Answer: x = 2 or x = -12 Thus the Answer is A.
