Y = a x² + b x + c
y = 0.0473809524 · 20² + 2.221428571 · 20 - 0.005952381 =
= 18.95236 + 44.42875 - 0.05952381 = 63.374978 ≈ 63.4
Answer: C ) 63.4 ft.
Answer:
How to make V the subject of the formula?
In the formula v = u + at, v is the subject.
To find v in the example, we substitute the values u, a and t in the R.H.S. of the equation.
To make 'u' the subject of the formula in v = u + at,
To make 't' the subject of the formula, v = u + at, ...
The volume of a cuboid is the product of length and breadth of the cuboid.

Step-by-step explanation:
Answer: C) Find the factors of c that add up to b.
==============================================
Explanation:
If we want to factor something in the form x^2+bx+c, then we look for two numbers that
-------------
Let's look at a specific example
Consider factoring x^2+5x+6
We need to find two numbers that...
- Multiply to c = 6
- Add to b = 5
Through trial and error, you should find the two numbers to be 3 and 2. This means it factors to (x+3)(x+2). The order of the factors doesn't matter.
You can use the FOIL rule or the box method to expand out (x+3)(x+2). You should get x^2+5x+6 again.
