First distribute the 3 so you'll have:
12+12x=12x+12
Next you subtract 12 from both sides and you'll get:
12x=12x
then you divide both sides by 12 and you get:
x=x
Answer:
x=32 makes this equation true
Step-by-step explanation:
Well first we have to solve this to see-
25=-7+x Add 7 to both sides to get x by itself
+7 +7 Adding 7 to -7 makes it 0 so it goes away
32=x This is our final answer
Answer: The answer is B

Answer:
9 1/2
Step-by-step explanation:
Answer:
(x-2), (x+2), (3x-5)
Step-by-step explanation:
Factors of 3: ±1, ±3
Factors of 20: ±1, ±2, ±4, ±5, ±10, ±20
Possible factors of the polynomial: ±1, ±2, ±3, ±4, ±5, ±10, ±20, .... (there's a lot more but you probably do not need to list them all)
Pick a number to divide the polynomial by (I picked 2)
(3x³-5x²-12x+20)÷(x-2) = 3x²+x-10
So (x-2) is a factor of f(x) = 3x³-5x²-12x+20
Factor 3x²+x-10 = (3x-5)(x-2) these are the other factors of f(x) = 3x³-5x²-12x+20
