Factor the following trinomial
[tex]9x^2-24x+16[/tex]
Please show work
Answers
=> 9x² - 24x + 16
Split the middle term(term with x) in such a manner so that the product of those parts is equal to the product of term with x² and constant. Here, those parts are 12 & 12 as 12*12 = 9*16.
=> 9x² - 24x + 16
=> 9x² - (12 + 12)x + 16
=> 9x² - 12x - 12x + 16
=> 3x(3x - 4) - 4(3x - 4)
=> (3x - 4)(3x - 4)
Method 2
=> 9x² - 24x + 16
=> (3x)² - 2(3x*4) + 4²
=> (3x - 4)²
=> (3x - 4)(3x - 4)
Method 3
In case if you can't find the factors of the middle term.
Say f(x) = 0, find the zeroes using quadratic formula. Zeroes of this eqⁿ are [-(-24) ± √24²-4(9)(16)] / 2(9) = 4/3 & 4/3
Therefore, f(x) = (x - 4/3)(x - 4/3) = (3x - 4)(3x - 4)/9
Ignore the numeric constant.
f(x) = (3x - 4)(3x - 4)

46 people are going to the beach. Nine people can ride in each van. How many vans are needed?
Answers
Answer:
6
Step-by-step explanation:
No. of people going to beach = 46 .
Using Unitary Method ,
9 people can go in one van .
1 person can go in 1/9
46 people can go in 1/9 * 46 = 5.1
Since vans can't be in fraction , 1 extra van for 1 person is need that is for 46th person .
So total number of vans = 5 + 1 = 6

Adding the two equations gives ...
x = -3
Substituting for x in the second equation gives ...

Choose two things that a rigid motion preserves.
Answers
Two things that a rigid motion preserves are: length and angle.
The two things that a rigid motion preserves are:
1. Length: A rigid motion preserves the length of objects. This means that the distances between points or the lengths of line segments remain the same after the rigid motion is applied.
For example, if you have a line segment AB of length 5 units, a rigid motion such as translation, rotation, or reflection will not change the length of AB.
2. Angle: A rigid motion preserves angles between lines or line segments. This means that the measure of an angle remains the same after a rigid motion is applied.
For example, if you have an angle ABC with a measure of 60 degrees, a rigid motion will not change the measure of angle ABC.
