Distribution is one of the most important terms of math you need to know.
Distributing, in this case, is when you take the -6 and multiply the terms in the parenthesis.
When you do that. You’ll get -78 = -6p+24.
*Remember: a negative times a negative is always positive. A positive times a negative is always negative. If you need more help with this tip, please feel free to reply if you need any better tips and tricks.
Now, you’re going to solve -78-24 (since you switch the sign when you bring one term to the opposite of the equation).
Then you’ll have -102 = -6p
Lastly, instead of multiplying, you divide -102 by -6.
Your final answer should be 17 = p (or flip it to make it p = 17).
P = 2(l+w)
substitute for P and l
12+8y = 2 (4x-2y+w)
distribute
12+8y = 8x -4y +2w
solve for w
subtract 8x from each side
12 +8y -8x = -4y+2w
add 4y to each side
12 +12 y -8x = 2w
divide by2
6 +6y-4x =w
the other side is 6+6y-4x
Answer:
where the parameter s is a real number and u=P1-P0 is a line direction vector. Using this representation P(0)=P0, P(1)=P1, and when s.ge-0.le-1, P(s) is a point on the finite segment P0P1 where s is the fraction of P(s)'s distance along the segment. That is, s = d(P0,P(s)) / d(P0,P1). Further, if s < 0 then P(s) is outside the segment on the P0 side, and if s > 1 then P(s) is outside the segment on the P1 side.
