Gregs parents tell him if he works more than 60 hours in May, they will buy him a new lawn mower. In the month of May, Greg earns $1,387-50. Are Greg's parents going to buy Greg a new lawn mower?How many hours did he work?Expain using math terms and words.​

how much money did he make an hour ?? you cant calculate hours if you dont know his rate

Step-by-step explanation:

total made / hourly rate = hours worked and then you can determine if he gets a lawn mower

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)
