Hi!
We will solve this using ratios, like this:
45,6 people per 3 square kilometers
x people per 1 square kilometer
_________________________________
x = (45,6*1)/3
x = 45,6/3
x = 15,2
Hope this helps!
Answer:
15.2
Step-by-step explanation:
3/45.6 = 1/x *Cross multiply.
3x = 45.6 *Divide both sides by 3.
x = 15.2
x = 142/83
y = 111/83
z = 452/83
-2, -5
h2 + 7h + 10 = 0
h^2 +7h + 10 = 0
h^2 +2h +5h + 10 = 0
h(h+2) + 5(h+2) = 0
h+2 = 0 or h+5 = 0
h = -2 or h = -5
10 - 4(6) (-4)
10 - 4(-24)
10 + 96 = 106
