You have to make it into a subtraction problem. 82-58=24
Answer:
the first one
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (10, - 6) and r = 6, hence
(x - 10)² + (y - (- 6))² = 6², that is
(x - 10)² + (y + 6)² = 36
Answer:
1152
Step-by-step explanation:
4 boys and 4 girls be arranged in a row such that no two boys and no two girls are next to each other.
Two boys and two girls are not next to each other. so one boy and one girl are next to each other in two ways.
