Answer:32-24n
Step-by-step explanation:
Take 8 and 4 and multiply it and you get 32. Take 8 and 3 multiply or add 8 three times and you get 24 and also add the n so it’s 24n since the n goes no where, and you can’t really subtract a number with a letter with a number or a number with a different letter, you can only subtract or add it if it has the same letter on the number. Hope that helps.
Answer:

Step-by-step explanation:
Hello, the Conjugate Roots Theorem states that if a complex number is a zero of real polynomial its conjugate is a zero too. It means that (x-4i)(x+4i) are factors of f(x).

The coefficient of the leading term is 1 and the constant term is -240 = 16 * (-15), so we a re looking for a real number such that.

We identify the coefficients for the like terms, it comes
a = -2 and 16a = -32 (which is equivalent). So, we can write in
.

The sum of the zeroes is 2=5-3 and their product is -15=-3*5, so we can factorise by (x-5)(x+3), which gives.

And we can write in 

Hope this helps.

Your answer: q=1.
-
Steps:
1.) Add q to both sides. (11 + q = 12 - q + q.)
2.) Simplify. (11 + q = 12.)
3.) Subtract 11 from both sides. (11 + q - 11 = 12 - 11.)
4.) Simplify again. (q = 1.)
