Answer:
yes, yes, no
Step-by-step explanation:
1. L= i + 2j +k; P = -3i + j + k, line lies on one another at k
2. L =i + 2j + k and P = 6i -3j + k, the lines lie on one another at k
3. P = ai + bj and -2bi +2aj + (a+b) k

Answer: C
Step-by-step explanation:
Okay first set a comparison since the two triangles are similar
x-1/20=x-1+27/3x+8
x-1/20 = x+26/3x+8
cross multiply
20x+520=3x^2+8x-3x-8
3x^2-15x-528=0
3(x^2-5x-176)=0
im kinda lazy to factor this out so i used an online calculator right here but factor it out like a good kid
x=16, x=-11
it has to be positive so x=16
C
