1. Use the above figure to answer the following questions. a. What is the intersection of plane P and plane R?
b. Name three points that are collinear
c. Name plane R in two more ways
d. Name four coplanar points
e. Name a point that lies on both plane P and plane R

i think the answer is b.

step-by-step explanation:

not 100% sure though.

answer: y=0 if that is what u r looking for

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

you,

mrb

(a + b) (a^2 - a b + b^2)

25/6 hope it : )
