Answer:
This would probely be 266.
Step-by-step explanation:
There are three kids so I would divide them by three. Or multiply 266 by three. Of course there would still be 2$ left.
Answer:
x = 5 ± 
Step-by-step explanation:
Given
x² - 10x + 25 = 35 ( subtract 25 from both sides )
x² - 10x = 10
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = 10 + 25
(x - 5)² = 35 ( take the square root of both sides )
x - 5 = ±
( add 5 to both sides )
x = 5 ± 
That is the second option on list
Answer:
D = sqrt[ (2-4)^2 + (7- (-1))^2] = ~8.2
Step-by-step explanation:
D = sqrt[ (Fx-Gx)^2 + (Fy- Gy)^2]
Area of a circle = 3.14 x r^2
=3.14 x 8.5^2
= 226.865
