The Answer is B Because i fu plug it in it works
Answer:
The zeroes are and
On the graph, each of these zeroes represent the x-value where the equation will intersect with the x-axis.
Step-by-step explanation:
We have the quadratic equation
To factor this we need to find two numbers that fulfill the following:
They add up to 1
They multiply to give you -20
These two numbers are -4 and 5
This means that the quadratic equation in its factored form will be:
Now that we have the factored form, we need to set and solve for x
From this factored form, we can see that when and the result will be zero. Just to check we can plug in each of these x values
The result of this confirms that x=4 and x=-5 are indeed the zeroes of this equation.
Each of these zeroes represent the x-value where the equation will intersect with the x-axis.
Answer:
x + 5 + x + 5
5 + 5 + x + x

Answer:
Sardar has a 29% chance of inheriting at least some money.
Step-by-step explanation:
Since Sardar has two old rich aunts, Betty and Gwenda, assuming they will both die before he does, for each aunt, Sardar thinks the chance that she will leave him some money if she dies first is 1/3, but Sardar thinks that if Gwenda dies first, the chance that Betty will leave him money is only 1/4, and if Betty dies first, the chance Gwenda will leave him money is also 1/4, to determine what is the probability that he will inherit at least some money by the time they both die the following calculation must be performed:
(1/3 + 1/4) / 2 = X
(0.333 + 0.25) / 2 = X
0.58333 / 2 = X
0.29 = X
Therefore, Sardar has a 29% chance of inheriting at least some money.
