Answer:
3x^2+5x+1
Step-by-step explanation:
(x^2 + 3x + 1) + (2x^2 + 2x)
Combine like terms
x^2 + 2x^2 + 3x +2x +1
3x^2+5x+1
V=<span>π r^(2)h
you put the number in the place of the R and H</span>
Do you multiply 2/3 And 1/6 what Ford The minus sign mean
Hey there! I'm happy to help!
First, let's find the slope of the two lines. To find the slope, you divide the difference in the y-values by the difference in the x-values.
LINE M
7-12/3-6=-5/-3= <u>5/3</u>
LINE N
1-6/-5+2=-5/-3=<u>5/3</u>
If lines have the same slopes, they are parallel because they are always moving at the same incline and therefore will never meet. This matches what answer A says.
Therefore, the correct answer is A) Lines m and n have the same slope so they are parallel.
I hope that this helps! Have a wonderful day!
