Answer:
OR 3cd + 3 and one-thirds c minus 3d
Step-by-step explanation:
Given the algebraic expression:

Combining like terms

The final expression gives the required answer on combining the like terms.
Answejust divide x on both terms and you left with 4x^2+3x then simple take a derivative which is 8x+3
Step-by-step explanation:
You can solve mean by adding up all the numbers then dividing it by the number of numbers there are.
You can solve the median by putting all of the numbers in order and then crossing off one in the beginning then crossing off one at the end. You can continue that until you get to one number in the middle.
You can solve the mode by looking for the most frequent number. That's the mode. You can remember that by looking at the MO and remember most often.
I hope this helps :-)
A door alarm works in 72 out of 100 cases.
surveillance camera works in 68 out of 100 cases.
The probability that method A is used = 72/100
The probability that method B is used = 68/100
Since both method are used we find the probability of A and B
Probability ( A and B) =
* 
=
