Answer: 3a^2+6ab+3b^2-2a-2b-1
Step-by-step explanation:
For G(x), we must plug in (a+b) into G(x):
G(a+b) = 3(a+b)^2-2(a+b)-1
= 3(a+b)(a+b)-2(a+b)-1
= factor: 3(a^2+ab+ab+b^2)- (2a+2b)-1
= multiply: 3a^2+3ab+3ab+3b^2-(2a+2b)-1
= now factor the last part: 3a^2+3ab+3ab+3b^2-2a-2b-1
= add/subtract: 3a^2+6ab+3b^2-2a-2b-1

f(x) = 3x - 5 and g(x) = 5x + 8. Find 3g(x) - 2f(x).
Answer:
9x + 34
Step-by-step explanation:
3g(x) - 2f(x); f(x) = 3x - 5 & g(x) = 5x + 8.
3(5x + 8) + - 2(3x - 5) (Plug g(x) & f(x) into equation)
15x + 24 + - 6x + 10 (Use distributive property)
9x + 34 (Combine like terms) - This is as much as it can be simplified.

Which equation has exactly one solution in common with the equation y=6x-2?
A. 18x - 3y = 6
B. 1/2y = 3x - 2
C. 2y = 4x - 12
D. 18x - 12 = 3y
Answer:
A. 18x - 3y = 6
Step-by-step explanation:
By taking 3 common from the terms 18x and 3y we get,
3 (6x-3y) = 6
or, 6x - y = 6/3
or, 6x - y = 2
And,
The equation becomes,
y = 6x - 2
The equation has exactly one solution in common with the equation y=6x-2 will be 18x - 3y = 6. The correct option is A.
What is a system of equations?A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
By taking 3 commons from the terms 18x and 3y we get,
3 (6x-3y) = 6
6x - y = 6/3
6x - y = 2
The equation becomes,
y = 6x - 2
Therefore, the equation has exactly one solution in common with the equation y=6x-2 will be 18x - 3y = 6. The correct option is A.

Safety regulations require that the time between airplane takeoffs (on the same runway) will be at least 4 minutes. When taking off, the run time of an airplane on the runway is 24 seconds. Planes are on average waiting 5 minutes and 54 seconds for take-off. On average there are 12 planes taking off per hour. How many planes are either on the runway or waiting to take off?
Answer:
1 plane either on the runway or waiting to take off
Step-by-step explanation:
We are given;
Frequency of take off = 12 planes per hour = 12/60 = 0.2 planes per minute
Waiting time on runway = 5 minutes 54 seconds = 5.9 minutes
Run time on runway = 24 seconds = 24/60 minutes = 0.4 minutes
To solve this question, we will use Little's law which is given by the formula;
System inventory = rate of flow × throughput time
Now, rate of flow is the same as Frequency of take off.
Thus, rate of flow = 0.2 planes per minute
Throughput time = Waiting time on runway + Run time on runway
Thus;
Throughput time = 5.9 minutes + 0.4 minutes
Throughput time = 6.3 minutes
Thus;
System inventory = 0.2 × 6.3 = 1.26 planes
Thus is approximately 1 plane.

[tex]81° + 3a = 180° \\ 3a = 180 - 81 \\ 3a = 99 \\ a = \frac{99}{3} \\ a = 33°[/tex]
The three angles of this triangle are :
[tex] \: ∠1 \:= 81° \\ \: \: ∠2 = 2a = 2 \times 33 = 66° \\ ∠3 = a = 33 \\ \\ ∴ \: a = 33° \: [/tex]
Solve this inequality. -y + 3 < 8 and y + 2 > 9
y+2>9
-2 on both sides
y>7
-y+3<8
-3 on both sides
-y<5
y is still negative so simply divide both sides by -1
y>-5
The inequality y > 7 represents the solution set of the given compound inequality.
What is inequality?
Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.
Given is the following compound inequality.
- y + 3 < 8 and y + 2 > 9
We have -
- y + 3 < 8 and y + 2 > 9
Now, first we will solve inequality (1)
- y + 3 < 8
- y + 3 < 8
- y + 3 - 3 < 8 - 3
- y < 5
y > 5
Solving inequality (2)
y + 2 > 9
y + 2 - 2 > 9 - 2
y > 7
We have two possible solution sets -
y > 5 and y > 7
To satisfy both the solution sets, the inequality y > 7 will be the final solution of the given compound inequality.
Therefore, the inequality y > 7 represents the solution of the given compound inequality.

Answer:
X= 60º
Step-by-step explanation:
If you are solving for a ∆, a ∆ has a degree of 180º. This thus when added up gets you.
81º + 39º = 120º
180º - 120º = 60º
Therefore in conclusion, X would be 60º.
Determine the preferred width of each class if you use 8 classes, a high of 87, and a low of 2. (this is a statistics question)
A. 15
B. 13
C. 11
D. 10
Answer:
11 ; C
Step-by-step explanation:
To get the class width, we start by finding the range of the data set
That will be; the highest number - the smallest number
= 87-2 = 85
We proceed by dividing the number of classes we want by this number
That will be 85/8 = 10.625
We now proceed to approximate this value to the nearest whole number = 11
Hence , 11 is the class width to use
