You need to substitute 9 with every x value in the equation.
So, 3(9)^2-7(9)+11
p(x)= 191
Answer x/3 -(-2)= 16
X/3+ 2=16
X/3=16-2
X/3=14
X= 14x3=42

Answer:
D
Step-by-step explanation:
Every millimeter is 1/10 of a centimeter, so 1 mm = 0.1 cm and 50 mm = 5 cm. This means that 25 mm can be re-written as 2.5 cm, and we can then find the difference by doing 25 - 2.5 = 22.5 cm. If you were looking for a different type of answer, you can also say that 25 mm is 10 times less than 25 cm.
I hope this helps!
