Hey there! I'm happy to help!
First we use the distributive property to undo the parentheses.
7n+12n-9-2
We combine the terms with n.
19n-9-2
And we combine the constants.
19n-11.
Have a wonderful day! :D
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{19n - 11}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{7n + 3(4n - 3) - 2}[/tex]
Distribute 3 through the parentheses
[tex] \longrightarrow{ \sf{7n + 12n - 9 - 2}}[/tex]
Collect like terms
[tex] \longrightarrow{ \sf{19n - 9 - 2}}[/tex]
The negative integers are always added but posses the negative ( - ) sign
[tex] \longrightarrow{ \sf{19n - 11}}[/tex]
Hope I helped!
Best regards! :D

How many solutions are in the following problems?
6x + 4x - 6 = 24 + 9x
25 - 4x = 15 - 3x + 10 - x
4x + 8 = 2x + 7 + 2x - 20
Answer:
Step-by-step explanation: Only one solution
To solve this, first combine like terms.
6x + 4x - 6 = 24 + 9x
10x - 6 = 24 + 9x
Then move all like terms to one side.
10x - 9x = 24 + 6
x = 30

Thank YouWILL MARK BRAINLIEST!!! please help me with this:)
Answer:
I believe it is C or D. (C) The IQR is the best measurement of spread for games and movies.
(D) The standard deviation is the best measurement of spread for games and movies.
The explanation why it could be D:
Measures of spread are stats that describes how separated are the group of data between each other.
The measures are range, quartiles, variance and standard deviation. Among these measures, the standard deviation is the one that best expresses the variation, dispersion or spread of a set of values, because is based on the difference between each data and the mean, it takes in count each separation.
The explanation why it could be C:
Our both box plots are highly skewed, therefore, the IQR is the best measurement of spread for games and movies and option C is the correct choice.
I believe it is C, my friend. So I would go with C.
I hope this helps.

The area of a square field is 42025 m square. Find the perimeter of the field. Can you explain and say it answer both pls
Answer:
Step-by-step explanation:
Answer:
820 m
Step-by-step explanation:
given:
The area of a square field is 42025 m square.
Find:
perimeter of the field.
solution:
Area of square = s² where s = side of square; A = 42,025 m²
plug in values into the formula:
[tex]\sqrt{42,025}[/tex] = s² ------square root
s = 205 m ---------length of each side of a square
solve for Perimeter:
Perimeter = 4 times the sides
= 4 x 205m
= 820 m
therefore, the perimeter of a square field is 820 m
7) Simplify

Find the perimeter of the rectangle.
Answer: 4m²-6m+12 or 2(2m²-3m+6)
Step-by-step explanation:
To find the perimeter, we use the formula [tex]P=2l+2w[/tex]. Since we are given the length and width, you plug them in and solve.
2(6-5m+6m²)+2(2m-4m²) [distribute]
12-10m+12m²+4m-8m² [combine like terms]
4m²-6m+12 or 2(2m²-3m+6)
Now, we know that the perimeter is 4m²-6m+12 or 2(2m²-3m+6).

The product of odd numbers is always even true or false ?
Answer:
false
Step-by-step explanation:
let's say we have two odd numbers
2k+1 and 2t+1
[tex](2k+1)(2t+1)\\\\=4kt+2k+2t+1\\\\=2(2kt+k+t)+1[/tex]
so we see it's odd
Answer:
false
Step-by-step explanation:
If we can show a counter example, then it would be false
3*5 ( both are odd numbers)
15 ( that is odd)
So it is not a true statement
Two submarines are underwater. The number -4,845 represents Submarine A's position (in feet) relative to the surface. The number -5,161 represents Submarine B's position (in feet) relative to the surface. Which submarine is closer to the surface? a Submarine A is closer to the surface. b Submarine B is closer to the surface. c Both submarines are at an equal distance away from the surface.
Answer
a
Step-by-step explanation:
because submarine b has a bigger negative number so its more further down
