Tommy has a pet monkey. every day, his monkey eats 4 apples in the morning. the monkey also eats two bananas for every banana that tommy eats.

write an equation to describe this situation where x is the number of bananas tommy eats and y is the total number of pieces of fruit the monkey eats.

The required equation is :

Step-by-step explanation:

Tommy's monkey eats 4 apples in the morning. The monkey also eats two bananas for every banana that Tommy eats.

Let Tommy eats x bananas, then the monkey eats 2x bananas.

Then, the required equation will be :

answer is x<

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)
