Are you asking for the letter or what the line is called because if it's just the letter then it is r if it is the name then its a plane intersect.
Step-by-step explanation:
I think we have to find the factors so
3x2 + 42x + 105
First we will multiply 105 by 3 = 315 then find factors of 315 which may add or subtract = 42
So 45 and 7
3x2 + 45x - 7x + 105
3x( x + 15) - 7(x - 15)
(3x - 7) and ( x - 15) are the factors
There is a problem please recheck the question
Slope is always (y2-y1)/(x2-x1) in this case:
(-2-3)/(6--4)
-5/10
-1/2
The answer is 5:) you first have to cross multiply then divide both sides from x
Answer:
It 12
Step-by-step explanation:
This is because the scale factor between the triangles is 1.75, so I divide 21 by 1.75 and got 12
Hope this helped
