8+x=L L+x=26 substitute (8+x)+x=26 x is the same for both expressions because the points are equally spaced solve for x, then solve for L
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
the points are evenly spaced, so L is the same distance away from both points B and E
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
So L is the midpoint of BE
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
do you see this?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
so we can say (B+E)/2 = L or basically take the value of B, add it to E, then divide by 2 to get L
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
what does that give you?
 one year ago

can we do number 4 please?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
what is the distance from point T to point E
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
good, now what's 2/3 of 15?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
so the distance from point T to point P is 10 units (since P is 2/3 of the way from T to E)
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
So just add 10 to the value of T to get your answer
 one year ago

hali12Best ResponseYou've already chosen the best response.1
thanks, im going to post more, maybe u can help me?
 one year ago

did you mean #5 through #9?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
and not #1 through #5
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
how did you get #3 to be true?
 one year ago

hali12Best ResponseYou've already chosen the best response.1
cause the line goes through the AM
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
does it? take a very close look at it
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
try to rotate it in your mind
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
better yet, get a piece of paper, label it and try it out
 one year ago

hali12Best ResponseYou've already chosen the best response.1
ohhhhhh i see its like putting a pencil through a peice of paper
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
exactly, so do they intersect?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
why is the last one false?
 one year ago

hali12Best ResponseYou've already chosen the best response.1
idk, i wanted to put true, but something was teling me to put false
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
do E, D and C all lie on the same line?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
so they are collinear by the very definition of collinear
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
points are collinear if they all lie on the same straight line
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
Example dw:1343852694256:dw
 one year ago

Example of noncollinear points dw:1343852731003:dw
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
Notice how there is no way to draw a straight line through all of the points, so those points are noncollinear
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
again tell me what you get
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
for #12 right?
 one year ago

yes, P is coplanar with T, R and Q

they all lie in the same plane (the back face)
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
no, what do the back face and the bottom face have in common (where do they intersect)?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
that bottom edge in the back is what they have in common
 one year ago

 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1

6 flat parts to the roof? or 6 total so far?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
ok, then count in the floor
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
there are 7 faces total
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
so there are 7 planes
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
with any geometric solid, a "face" is also a plane
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
points D, J and A all lie on the left wall (that's behind the front and right walls...so it's hidden from view)
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
what also lies on that left wall?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
i and f don't because they lie on the left rooftop

draw a line from D to J
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
which face does this line lie in?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
another way to name JADG is JAD since 3 points are enough to make a plane
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
yes, JIG is the same plane as JGF and they both work
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
but JGF is the only listed answer, so it's JGF

number 18 "No answer is correct."?

there is no face that has the line

hali12Best ResponseYou've already chosen the best response.1
noncoplanar ( number 19)
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
are you sure? look again (very closely)
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
do they all lie on the same line?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
good, so #19 is noncollinear
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
yes, very good
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
not all of those 3 points lie in the same plane/face
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
good, from 20, A, B and G are noncoplanar, so throwing in another point (whatever that new point may be) will not change this
 one year ago

hali12Best ResponseYou've already chosen the best response.1
22  They don’t intersect.
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
do they all lie on the same line?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
so they do NOT lie in the same plane?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
are you sure?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
yes you are correct
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
they all lie on the same line?
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.1
so not colllinear
 one year ago

hali12Best ResponseYou've already chosen the best response.1
