12 = 12/1 = 24/2, 24/2+1/2=25/2 so 25/2, and it's in simplest form because 2 can't go into 25
28/2=14
12/2=6
So it's half perimeter is 20
By trial and error the only possible solution is
8 * 12 = 96
Answer:
option 4
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
(- 4, - 1 ) → (4, - 1 )
(2, 6 ) → (- 2, 6 )
Step-by-step explanation:
X= 4-3y/y-5
x(y-5) = 4-3y
xy -5x = 4 -3y
xy+3y = 4+5x
y(x+3)= 4+5x
y = (4+5x)/(x+3)
