Answer:
[tex]3x(x-4)[/tex]
Step-by-step explanation:
[tex]3x^2-12x[/tex] cannot be factorised in the form (x+b)(x-b) unless one of the b's is zero, so I wonder if the expression is incomplete?
To factorise [tex]3x^2-12x[/tex], take out the common factor [tex]3x[/tex]:
[tex]\implies3x(x-4)[/tex]
Therefore, x = 0 and x = 4
- - - - - - - - -
[tex]3x^2-12x[/tex] factorised in the form (x+b)(x-b) would be [tex](3x+0)(x-4)[/tex]
but it is not usual to have a zero in a factorised form.

How many license plates in Ontario were registered between the following licence plates? As the question is asking for plates between the given ones, you should consider that these plates are NOT included in the range. From: AVVJ 144 To: BVNP 199
The number of plates is an illustration of permutation and combination
The number of plates is 2592
How to determine the number of platesThe range is given as: AVVJ 144 To: BVNP 199 (exclusive)
From the range, we have the following highlights:
The first letter can be either A or B (i.e. 2 letters)The second letter can be only V (i.e. 1 letter)The third letter can be from W to M (24 letters)There are 54 numbers between 144 and 199The number of plates (n) is then calculated as:
[tex]n = 2 * 1 * 24 * 54[/tex]
Evaluate the product
[tex]n = 2592[/tex]
Hence, the number of plates (n) is 2592

Find the Area of the figure below, composed of a rectangle and a semicircle.
Round to the nearest tenths place.
Answer:
68.1 units²
Step-by-step explanation:
Start by finding the area of the rectangle...
[tex]Area=lw\\Area=6*9\\Area=54[/tex]
Then, find the area of the semicircle...
[tex]Radius=\frac{1}{2}*Diameter=\frac{1}{2}*6=3[/tex]
[tex]Area=\frac{1}{2}\pi r^2\\Area=\frac{1}{2}\pi 3^2\\Area=\frac{1}{2}\pi 9\\Area=\frac{9}{2}\ pi\\Area\approx14.1[/tex]
Now, add the two to get...
54+14.1=68.1

Four-tenths of the 20 children in the park are playing soccer. How many children are playing soccer in the park?
Four-tenths = 4/10
So, 4/10 of the 20 children in the park are playing soccer.
We can find out how many are playing by taking 20 x 4/10 (the portion)
20 x 4/10 = 8, so there are 8 children playing soccer in the park.

How to calculate the total area of a figure?Area and perimeter are calculations aimed at the measurements of a geometric figure. The area is the size of the surface, and the perimeter is the sum of its sides. In general, to find the area, the base of the figures is multiplied by the height (h).
So we have that:
[tex]As = (28*28) - (\pi(14)^2)\\As= 168 cm^2[/tex]

Which function is represented by the graph? f(x) = –|x| 4 f(x) = –|x| – 4 f(x) = –|x 4| f(x) = –|x – 4|.
The function which is represented by the graph attached below shifted 4 units right is similar to option d, which is,
[tex]f(x)=-|x-4|[/tex]
What is a graph of function?The linear function has the highest power of the unknown variable one. Thus, the graph plotted for the linear function is a straight line.
Types of function movement over the graph -
Horizontal shift- Let the parent function is [tex]f(x)[/tex]. Thus by replacing parent function with [tex]f(x-b)[/tex] shifts the graph b units right and by replacing parent function with [tex]f(x+b)[/tex] shifts the graph b units left.Vertical shift- Let the parent function is [tex]f(x)[/tex]. Thus by replacing parent function with [tex]f(x)-c[/tex] shifts the graph b units down and by replacing parent function with [tex]f(x)+c[/tex]shifts the graph b units up.The graph given in the problem is attached below. All the parents function of the options are absolute function.
In the graph, the parent function 4 units shifted to right. So the -4 should add in the parent function. Thus, by the above definition, this is a horizontal shift of the function and can be written as,
[tex]f(x)=-|x-4|[/tex]
Hence, the function which is represented by the graph attached below shifted 4 units right is similar to option d, which is,
[tex]f(x)=-|x-4|[/tex]

If a car moving east has a velocity of 50 (mph) what number could we use for the velocity of a car traveling the same speed in the opposite direction?
Answer:
We could use the number -50 miles per hour east for the velocity of a car traveling at the same speed in the opposite direction. Velocity means speed in a certain direction, so if an object goes at an opposite direction, the speed is therefore negative.
