please help :) (1) Beekeepers began reporting devastating bee losses beginning in 2006—sometimes as much as 90 percent of their hives! (2) Most of the bees were gone. (3) This phenomenon is called Colony Collapse Disorder, or CCD. (4) Scientists remain unsure of what causes CCD, but they know that it has happened before. (5) Reports of disappearing bees date from the 1800s. Which revision would make the paragraph more precise? A. Sentence 2: Change “were gone” to “had simply vanished.” B. Sentence 3: Change “phenomenon” to “thing.” C. Sentence 4: Change “remain” to “continue to be.” D. Sentence 5: Change “date from” to “come from as far back as.”

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.

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,

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

the answer to your question is b.
