If you would like to solve 16x^2 - 81 = 0, you can calculate this using the following steps:
<span>16x^2 - 81 = 0
</span>(4x - 9) * (4x + 9) = 0
1. 4x - 9 = 0 ... 4x = 9 ... x = 9/4
2. 4x + 9 = 0 ... 4x = - 9 ... x = - 9/4
The correct result would be: <span>x = 9 over 4, x = −9 over 4.</span>
Answer:
You have three card : 3, 4, and 5.
You first pick one card randomly, the probability of picking a 3 is:
P = 1/3
You then pick a second card without putting the first card back, the probability of picking a 5 is:
P = 1/2
=> The probability of picking a 3 and then picking a 5:
P = (1/3) x (1/2) = 1/6
Hope this helps!

Answer:
First 15+4 which equal 19 and then multiply by 3 which equal 57
Step-by-step explanation:
To find g (f(x)) you should substitute "4x^2+x+1" to "x" of g(x) function. You'll havew:

To count (4x^2+x+1)^2 Just assume ( [4x^2+x] + 1)^2 and use the (a+b)^2=a^2+2ab+b^2 formula, where a=4x^2+x and b=1
<span>The solution would
be like this for this specific problem:
