Step-by-step explanation: The first step when factoring any polynomial is to factor out the GCF. The GCF is the greatest common factor for all the terms of the polynomial. By factoring out the GCF first, the coefficients and constant term of the polynomial will be reduced.
Answer:
16/45
Step-by-step explanation:
Step 1: When dividing fractions, use “KFC”. It means Keep the first fraction, Flip the second one, and
Change it to multiplication
-4/20 ÷ -9/16 → -4/20 ∙ 16/-9
Step 2: Reduce any fractions if necessary, it makes multiplying them easier and you will have to reduce anyway at the end. It’s easier arithmetic to reduce at this step. The first fraction reduces because both the numerator and denominator are divisible by 4.
-1/5 ∙ 16/-9
Step 3: Multiply numerators and denominators together to get one fraction
(-16)/(-45)
Step 4: Cancel out the negatives, a negative divided by a negative is a positive. Our final answer is
16/45
Answer is C:9
12^9/12^5 = 12^4

Isolate the x.
Do the opposite of PEMDAS. Note the equal sign. What you do to one side, you do to the other.
2/3x - 2 = 7
Add 2 to both sides
2/3x - 2 (+2) = 7 (+2)
2/3x = 9
Multiply 3/2 to both sides to isolate the x
2/3x(3/2) = 9(3/2)
x = 9(3/2)
Multiply 9 with 3, and divide by 2
9 x 3 = 27
27/2 = 13.5
x = 13.5 is your answer
