Answer:
3n+12
Step-by-step explanation:
(n+4)3=
3n+12
Just multiply the number and variable inside the parentheses by 3
Answer: 9x-3x and 5x+x
Step-by-step explanation:
1. Brianna's thinking is incorrect because of course, when x is 0, the expression will equal whatever value isn't an x term. To find equivalent expression, you actually need to find which expressions have the same amount of x terms and the same value.
2. Expressions A and C are equivalent.
3. Expression A can be simplified, as you can do 9x - 3x = 6x, so your final expression would be 6x - 4. Expression C can also be simplified with 5x + x = 6x, which can then also be written as 6x - 4. This means both expressions have the same amount of x terms, and the same value, so they are equivalent.
Answer:
Both questions are true.
Step-by-step explanation:
The general mathematical equation of a line can be written as 
.
If we rearrange the two equations given in the question as follows:
and 
We can see that they follow the general equation we defined earlier so we can say that they represents linear lines.
The 
given in the second question also represents a similar linear line with a different slope.
So the two questions are both true.
I hope this answer helps.
Answer: You would have 50 quarters and 20 dimes
Step-by-step explanation: 50-30=20 so, 20+50=70
