The Pacific Ocean = 46% of Earth (P = 46%)
The Land on Earth = 54% of Earth (E = 54%)

One Fence Per Yard = $1.75
$73.50 - $3.50 (The Tax) = $70
$70 Divided by $1.75 = 40 Yards
Change in temperature = 12 - (-13) = 12 + 13 = 25
Number of hours = 25/5 = 5 hours.
Required time = 4 am + 5 hours = 9.am

Answer:
x=-3, x=1, x=8
Step-by-step explanation:
When you have to find the zero of an equation like (x+3) all you have to do is solve for x.
x+3=0 equal the equation to zero
x+3-3=0-3 cancel out 3
x=-3 answer
If you have to find the zero of an equation like f(x)=-2x^2 - 5x + 7 then you would have to factor the equation.
7*-2=-14 multiply
-7 & 2 find the two numbers that when multiplied =14 and when added = -5
(2x^2 + 2) (-7x + 7) replace -5 with -7 & 2
-2x (x - 1) -7 (x - 1) factor
(x - 1) (-2x - 7) rewrite
1st: x - 1 = 0
x = 1 : Answer
2nd: -2x - 7= 0
-2x - 7 + 7 = 0 + 7
-2x = 7
-2x / -2 = 7 / -2
x = 7 / -2 : Answer
