Factor 125x3 + 343y3

Mathematics
1 answer:
Annette [7]2 years ago
5 0

Answer:

(5x + 7y)(25x² - 35xy + 49y²)

Step-by-step explanation:

125x³ + 343y³ ← is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b² )

125x³ = (5x)³ ⇒ a = 5x

343y³ = (7y)³ ⇒ b = 7y

125x³ + 343y³

= (5x + 7y)((5x)² - (5x × 7y) + (7y)²)

= (5x + 7y)(25x² - 35xy + 49y²) ← in factored form

When rounding to the nearest hundred, which of the following numbers round to 400?
shepuryov [24]

The answer is 423 since it's the closest number to 400 from all the numbers listed above.

The numbers 351 and 445 would also round to 400 but they are not the closest ones.


Hope it helped,
