30+25=55
Answer:
(6+5a)/ (-5 +15a)
Step-by-step explanation:
h(x) = (6+x) / (-5+3x)
Let x = 5a
h(5a) =(6+5a) / (-5+3*5a)
= (6+5a)/ (-5 +15a)
D = sq.root of((x2 - x1)^2 + (y2 - y1)^2)
sq.root of 13 = sq.root of((x - (-2))^2 + (1 - 3)^2)
= sq.root of((x + 2)^2 + (-2)^2)
= sq.root of (x^2 + 4x + 4 + 4)
= sq.root of (x^2 + 4x + 8)
Now if we square both sides:
x^2 + 4x + 8 = 13
x^2 + 4x - 5 = 0
(x + 5)(x - 1) = 0
x = -5 or x = 1
Because when you divide both sides by a negative number, the inequality sign changes.
