There are one number is X, and another number is -9/10and sum is 2/3.
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
Answer:
the blank is p
Step-by-step explanation:
mulitplying but r and dividing by r cancel each other out, so you would be left with p=p
I don’t see no options? But if you simplify the answer is -30x^2 - 4x + 8 hope it helps
3 pennies = 3
12 dimes = 120
1 nickel = 5
120 + 5 + 3 = 128, so the number of pennies is 3.
Hope this helps!
