Answer:
50
Step-by-step explanation:
Let the numbers be 3x, 4x, 5x
(3x)^3 + (4x)^3 + (5x)^3 = 216000
27x^3 + 64x^3 + 125x^3 = 216000
216x^3 = 216000
x^3 = 1000
x = 10
5x = 5(10) = 50
Answer: 50

Answer: =
6x^2−5x−6
Step-by-step explanation: Multiply each term in one expression times each term in the other, then simplify by combining like terms.
Here are the like terms : =(3x+2)(2x−3)=3x(2x+3x(−3)+2(2x)+2(−3)
= 6x^2−9x+4x−6
=6x2−5x−6
Answer:
