Jessica planted a rosebush in her garden. The rosebush has a height of 30 cm. Each month the rosebush increases by cm. Which equation can be used to determine the height of the plant in centimetres, y, after x months? A) y = 30 - 6x
B) y = 6x - 30
C) y = 6x + 30
D) y = 6(x - 30)

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

it is a secret for it not to be compromised sorry

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)
