Answer: Second option.
Step-by-step explanation:
It is important to remember the Distributive Property in order to solve this exercise.
The Distributive property states that:

In this case you have the following expression provided in the exercise:

Then, in order to write this expression in another way, you can apply the Distributive property. Multiply each number inside the parentheses by "t".
Applying this procedure, you get:

Notice that this expression matches with the one shown in the the second option.
Answer:
The standard form of the quadratic equation is x² + 3·x - 4 = 0
Step-by-step explanation:
The standard form of a quadratic equation is a·x² + b·x + c = 0
Given that the expression of the quadratic equation is (x + 4)·(x - 1) = y, we can write the given expression in standard form by expanding, and equating the result to zero as follows;
(x + 4)·(x - 1) = x² - x + 4·x - 4 = x² + 3·x - 4 = 0
The standard form of the quadratic equation is x² + 3·x - 4 = 0

Answer:
8\sqrt{2}\ units.
Step-by-step explanation:
Use the trignometric property.
sin\theta = \frac{Perpendicular}{Hypotenuse}
Perpendicular = 8
Hypotenuse = h
\theta = 45^{\circ}
sin\ 45^{\circ} = \frac{1}{\sqrt{2}}
\frac{1}{\sqrt{2}} = \frac{8}{h}
h = 8\sqrt{2}\ units

Answer:
Remaining tickets left to distribute, A = (300 - 10m)
Step-by-step explanation:
a) Let the number of choir members be m
Let the number of tickets remaining after the distribution be A
Each choir member is to get 10 tickets each.
Number of tickets to be given to the members = 10m
original number of tickets = 300
So, number of tickets remaining after distribution, A = 300 - 10m (provided that m ≤ 30)
b) The independent variable in this expression is m (the number of choir members)
And the dependent variable is A (the number of tickets left after the distribution which depends on the number of choir members, m)
Hope this Helps!!!
