Answer:
11
Step-by-step explanation:
because the length of 12 is the same of t+1 so 11+1=12

Answer:
Step-by-step explanation:
Total number of days
The number of days she bought a banana or orange
The probability of buying a banana or an orange is
- P(b or o) = 21/30 = 0.7 = 70%
You can factor this by taking out the GCF (greatest common factor).
In the expression, the greatest common factor between the two terms is 5.
Take out 5:
5(2b + 5)
Is it possible to factor 2b + 5 even more?
No. So, your answer is D. 5(2b + 5).
Answer: The answer is 8.
Step-by-step explanation: The first step is to convert the expression into figures. We shall call the unknown number Y. So if we are told “the square of a number,” that means Y squared, or better still, Y^2. Further we are told “the difference between the square of a number and 40” and that can be written as;
Y^2 - 40.
Next we are told that this expression is equal to 3 times that number (that is 3Y). That can now be written out as follows,
Y^2 - 40 = 3Y
If we move all expressions to one side of the equation, what we would have is,
Y^2 - 3Y -40 = 0
(Remember that when a positive value crosses to the other side of an equation it becomes negative and vice versa)
We now have a quadratic equation
Y^2 -3Y - 40 = 0
By factorizing we now have
(Y -8) (Y + 5) = 0
Therefore Y - 8 = 0 or
Y + 5 = 0
Hence, Y = 8 or Y = -5
Since we are asked to calculate the positive solution, Y = 8
