Answer:
2x(2x - 3)
Step-by-step explanation:
Given:
(3x^2+2y^2-3x)+(2x^2+y^2-2x)-(x^2+3y^2+x)
Written as:
(3x² + 2y² - 3x) + (2x² + y² - 2x) - (x² + 3y² + x)
= 3x² + 2y² - 3x + 2x² + y² - 2x - x² - 3y² - x
Collect like terms
= 3x² + 2x² - x² + 2y² + y²- 3y² - 3x - 2x - x
= 4x² + 0 - 6x
= 4x² - 6x
= 2x(2x - 3)

Step-by-step explanation:
Here, we want to get what 6n means in the given context
Mathematically when calculating profit, we have to subtract the cost from the revenue
The revenue refers to the money made ;
From the question, $6 tickets were sold to a total of n people
The money made from these sales will be the product of the cost of each ticket by the number of people who bought the ticket
That will be $6 * n = $6n

There are 24 boys and 16 girls in a hall, each holding coins in their hand.The mean number of coins for the children is 11, The mean number of coins for the boys is 9 Work out the mean number of coins for the girls.
Answer:
14
Step-by-step explanation:
The computation of the mean number of coins for the girls is shown below:
Since there are 24 boys and 16 girls so the total children is 40
So the number of coins for all children is
= 40 × 11
= 440
And, the number of coins for all boys is
= 9 × 24
= 216
Now the mean is
= (440 - 216) ÷ 16 girls
= 14

A certain man has a negative balance of P250 in his back account b) suppose he deposits P300 in his back account ,what is the current balance in his account?
Answer: $50
Step-by-step explanation:
From the question, we are informed that a certain man has a negative balance of P250 in his back account and that he then deposits P300 in his back account.
The current balance in his account? will then be gotten by adding the negative balance of $250 to the $300 deposited. This will be:
= -$250 + $300
= $50
Therefore, his current balance will be $50

The length of two sides of a right triangle are leg:
10 m and hypotenuse: 15 m.
Find the length of the third side.
Answer:
11.2m
Step-by-step explanation:
Using Pythagoras,
a²+b²=c²
10²+b²=15²
100+b²=225
b²=225-100
b²=125
b=√125
b=11.2m
find the value of the variable if necessary round your answer to the nearest tenth
Answer:
x = 24.7
Step-by-step explanation:
Here, we want to find the value of x
To do this, we are to use the appropriate trigonometric ratio
From what we have;
9 faces the angle given as it is the opposite, x is below and it is the adjacent
The trigonometric identity that links opposite to adjacent is the tan which is the ratio of former to latter
Thus, we have that;
tan 20 = 9/x
x = 9/tan 20
x = 24.7
