Answer:
x= 3±sqrt(15)
Step-by-step explanation:
x^2 -6x = 6
Take the coefficient of x
-6
Divide by 2
-6/2 = -3
Square it
(-3)^2 = 9
Add this to each side
x^2 -6x+9 = 6+9
(x-3)^2 = 15
Take the square root of each side
sqrt((x-3)^2) = ±sqrt(15)
x-3 = ±sqrt(15)
Add 3 to each side
x-3+3 = 3±sqrt(15)
x= 3±sqrt(15)
Break this problem down first. You have two lines each with length of 5. You also have two halves of a circle, combine them to get a full circle with a radius of 2. The formula to find the perimeter of a circle is
and this gives a perimeter of 12.566 for the circle. Add this to your sides and you get a total of 22.566 which is answer B

Answer:
A = 250(1 + 0.016)^0.75.
Step-by-step explanation:
9 months = 0.75 years
So A = 250(1 + 0.016)^0.75.
