Which of these statements are correct about a line segment with a length of 12 units in a coordinate plane? Select all that apply. If it is reflected across the y-axis, its length will still be 12 units.
If it is rotated 270° about the origin, its length will still be 12 units.
ОООООО
If it is translated 15 units up, its length will still be 12 units.
If it is translated 18 units to the right, its length will no longer be 12 units.
If it is rotated 90° about the origin, its length will no longer be 12 units.
If it is reflected across the line y = -x, its length will no longer be 12 units.

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

what are ur choices?

da freeck kinda math is this just drop out

step-by-step explanation:

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)

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