The form of the sum of cubes identity is a³ + b³ = (a + b)(a² - ab + b²) ⇒ A

Step-by-step explanation:

To find the form of the sum of cubes identity ⇒ x³ + y³

Then the form of the sum of cubes identity is x³ + y³ = (x + y)(x² - xy + y²)

∵ a³ + b³ is a sum of two cubes

→ By using the same steps above

∵ = a and   = b

∴ The small bracket is (a + b)

∵ Square a = a² and square b = b²

∵ a × b = ab

∴ The big bracket is (a² - ab + b²)

∴ The form of the sum of cubes identity is a³ + b³ = (a + b)(a² - ab + b²)

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
