Number of three digit pins possible if zero an be the first digit and the numbers can be repeated is given by
Thus, the probability that Mr Jones and Mrs Smith select the same pin is given by
Basically what you have to do is multiply the two numbers that are mentioned and that will be your answer.
This is because the item will have the same amount or length and you just need to find what it will be with multiple ones.
Next time you could highlight keywords that help you understand if you are supposed to multiply, divide, subtract, or add.
Step-by-step explanation:
(-3x-2/x) multiply by (-15x+12/x)

Answer: 205</h3>
===========================================
Work Shown:
Recall that is the imaginary unit. Squaring both sides gets us
You can verify the answer using a tool like WolframAlpha.
Answer:
m = 3; b = -12
Step-by-step explanation:
In order to answer the question definitively, we must assume you intend for the equation to be an identity.
6(2x -5) -(mx +2) = 9x +b
12x -10 -mx -2 = 9x +b
Equating x terms:
12x -mx = 9x
12 -m = 9 . . . . . . divide by x; next, add m-9
12 -9 = m = 3
Equating constant terms:
-10 -2 = b
-12 = b
