I need to know what this means ​

Answer:   (5n - 8)(n² - 3)

<u>Step-by-step explanation:</u>

You can factor this using the Grouping Method (hint: rearrange the terms)

   5n³ - 8n² - 15n + 24

=  5n³ - 15n   -8n² +24

=  5n<u>(n² - 3)</u>   -8<u>(n² - 3)</u>

= (5n - 8)(n² - 3)

Which equation represents this sentence? One-half the sum of a number and four is three less than the quotient of five and the n
ehidna [41]

Answer:

Step-by-step explanation:

"one half the sum of a number and 4" is (1/2)(n + 4)

"three less than the quotient of 5 and the number" is 5/n - 3

putting this all together, we get

(1/2)(n + 4) = (5/n) - 3

Math help 20 points and brainliest
Dima020 [189]

Use distribution to find the answer to this one.

5x * 6x² = 30x^3

5x * 3x = 15x²

5x * 7 = 35x

-1 * 6x² = -6x²

-1 * 3x = -3x

-1 * 7 = -7

30x^3 + 15x² + 35x - 6x² - 3x - 7 → simplify this using like terms (look at the exponent of x and if there even is one)

30x^3 stays becuase there is no other like terms

15x² - 6x² = 9x² becuase they are like terms

35x - 3x = 32x because they are like terms

-7 stays because ther is no other like terms

Put these together in the final answer: 30x^3 + 9x² + 32x - 7

Hope this helps!
