Step-by-step explanation:
Given
x² - 9x + 20 = 0
x² - ( 4 + 5) x + 20 = 0
x² - 4x - 5x + 20 = 0
x ( x - 4 ) - 5 (x - 4 ) = 0
(x - 4 ) ( x - 5 ) = 0
Either
x - 4 =0
x = 4
or
x - 5 =0
x = 5
x = 4 and 5
Hope it will help :)

Answer:
18 times
Step-by-step explanation:
Sample space ; roll of 2 number cubes = 6^2 = 36
Sum of 4 in 2 cube rolls = 3
Probability = required outcome / Total possible outcomes
P(sum of 4) = 3 / 36 = 1 / 12
If number cube is rolled 216 times :
Probability on 1 roll * Number of rolls
(1 / 12) * 216
0.0833333 * 216
= 18
we are given

Firstly, we will simplify it


At x=5.5:
we can plug x=5.5


At x=5.1:
we can plug x=5.1


At x=5.05:
we can plug x=5.05


At x=5.01:
we can plug x=5.01


At x=5.005:
we can plug x=5.005


At x=5.001:
we can plug x=5.001


At x=4.9:
we can plug x=4.9


At x=4.95:
we can plug x=4.95


At x=4.99:
we can plug x=4.99


At x=4.995:
we can plug x=4.995


At x=4.999:
we can plug x=4.999


Answer:
4/3 i think
Step-by-step explanation:
(2+14)/(3+9)
Answer:
The equation is f = z - x
Step-by-step explanation:
The equation is
Given that
The total cost + online fee for one ticket is $32.25
Let us assume f be the cost of ordering each ticket online
Cost of each ticket be x = $24.95
And, the total cost = z = $32.25
Now the equation would be
x + f = z
So for f it would be
f = z - x
