saves $225 per month. which equation shows
how much money lani has in her account
after m months? select yes or no.
6. v
450 m
а
у =
yes
no
b y = 450m + 225m
c y = 450 + 225m
o yes
yes
no
no

C

Step-by-step explanation:

450 is her initial value

225 is her rate of change or constant rate

i think is g(1)=-1.

hope that i can

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)
