Which of the following best describes the solution to the equation below? 3(x+ 7) = 3x + 21​

Mathematics
1 answer:
Alexus [3.1K]3 years ago
3 0

Answer:

x = x; the solution has infinite solutions

Step-by-step explanation:

3(x+ 7) = 3x + 21​; distribute the 3 on the left side

3x + 21 = 3x + 21; now subtract 21 from both sides

3x = 3x; divide by 3

x = x; the solution has infinite solutions.  Since both terms are equal any value for x will be true on this equation.

Distributive property of <br>4x 567​
Maksim231197 [3]

567 = 500+60+7

4*567 = 4*(500+60*7)

4*567 = 4*500 + 4*60 + 4*7 ... see note below

4*567 = 2000 + 240 + 28

4*567 = 2268

--------

note: multiply the outer term 4 by each term inside the parenthesis to use the distributive property. The general distributive property is a*(b+c) = a*b+a*c. This can be extended to a*(b+c+d) = a*b+a*c+a*d. You can have as many terms as you like inside the parenthesis.

Verify whether the indicated numbers are zeroes of their corresponding polynomials.
Mashcka [7]

Answer:

  • No, incorrect

Step-by-step explanation:

<u>Given</u>

  • Q(s) = -4s^3 + 7s^2 - 24;
  • s = -4 and 1

<u>Verifying zeroes</u>

Q(-4) =

  • -4(-4)^3 + 7(-4)^2 - 24 =
  • 256 + 112 - 24 =
  • 344
  • Incorrect as 344 ≠ 0

Q(1) =

  • -4(1)^3 + 7(1)^2 - 24 =
  • -12 + 7 - 24 =
  • -29
  • Incorrect as -29 ≠ 0
