Answer:

1914

Step-by-step explanation:

Substitute "a" for 9 in the equation. Solve using the BEDMAS order (brackets, exponents, division, multiplication, addition, subtraction).

24a² - 30

= 24(9)²-30 The exponent only belongs to the 9. Square 9.

= 24(81) - 30 Multiply 24 and 81.

= 1944 - 30 Subtract 30 from 1944.

= 1914 Answer

24a²-30 at 9 is 1914.
