If 81 came out, what was dropped in?
I have rewritten the problem to 
but do not know how to solve it.
Answers
81 = 3 x 3 x 3 x 3 = 3^4.
So you have to solve:
3^x = 3^4
exponents have to be the same, so
x=4
That's mean that A(4) = 81

Answer: x = 1
Step-by-step explanation:
So you need to get x completely alone, so take c out of it by subtracting c
-3x = -3 -2c
x = 1 +2/3c
so you would plug that in to solve for C
So you know what x is (or the substitute for it right now)
-3(1 + 2/3c) + 2c = -3
multiply or add
-3 - 2c + 2c = -3
c is 0 when you combine
-3x + 0 = -3
-3x = -3
x = 1
x ≥ −8
x ≥ −2

Final answer:
The student's answer is incorrect because they failed to factor out a common factor of 8. The correct factorisation of the trinomial 8x^2 -8x-16 is 8(x - 2)(x + 1).
Explanation:
The student's answer of (x-2)(x+1) is incorrect for the trinomial 8x^2 -8x-16. The first step in factoring a trinomial is to look for a common factor in all terms. In this case, we have a common factor of 8, so we can rewrite the trinomial as 8(x^2 - x -2). Then we can factorise the quadratic equation, x^2 - x - 2, within the parenthesis using the general formula ax²+bx+c = 0, where the solutions or roots can be calculated using the formula -b ± √b² - 4ac over 2a. Factoring this equation gives us (x - 2)(x + 1) but because of the initial 8 we factored out, the correct factoring of the trinomial would be 8(x-2)(x+1).

Step-by-step explanation:,,
Answer:
The answer is B:subtract 1,add x,divide by 4
The other answer is D:add x,subtract 1,divide 4
Step-by-step explanation:
when you subtract 1 you isolate 3x so the equation looks like 3x=-x+3
the next step is to add x to both sides so you isolate the x to one side after doing that your equation should look like 4x=3,after this you divide both sides to the solution x=
The answer is also D because if you add x to both sides u isolate x to the left side so the equation will look like 1+4x=4 the next step will be to subtract one from each side and after doing this the equation should look like 4x=3 which should look familiar because its the same exact solution as B was so the answer to this choice is x=
With that evidence I can reasonably say that answer to the question is B,and D
