Expand to find the value of c
Notice that we get back the first two terms, the and the .We need to get rid of the last term of '9' as the term was not in the original form. The final form will look like
Hence,
(b)
(c) , square root both sides plus and minus of 2 Hence

Answer:
x = 4
Step-by-step explanation:
Solution:
-3(4x + 3) + 4(6x + 1) = 43
-12x - 9 + 24x + 4 = 43
12x - 5 = 43
12x = 43 + 5
12x = 48
x = 48 / 12
Therefore, x = 4
PLEASE MARK ME AS BRAINLIEST!!!
In the first 10 -> 10 - 9 = 1 (contain a 3).
In the first 100 -> 100 - 9 * 9 = 19 (contain a 3).
In the first 10^n ->
10^n - 9^n (contain a 3).
<u>The answer is 3.439 numbers contain a 3 in the first 10.000</u>
