Answer:
length, width, and height are (b+2), (b-2), (b+3)
Step-by-step explanation:
Doing what the problem statement tells you to do, you get ...
(b^3 +3b^2) -(4b +12)
= b^2(b +3) -4(b +3) . . . factor each pair of terms
= (b^2 -4)(b +3) . . . write as a product
= (b -2)(b +2)(b +3) . . . use the factoring of the difference of squares
The three factors are (b-2) , (b+2) , and (b+3). We have no clue as to how to associate those with length, width, and height. We just know these are the dimensions of the box.
Answer:

Step-by-step explanation:
Our sample space is the total number of cards in a deck, n(S)=52
Event A: Event that she chooses a three card
Number of 3 cards in a deck, n(A)=4
Event B: Event that she chooses a seven card.
Number of <u>7 cards</u> in a deck, n(B)=4
In Probability, P(A or B)=P(A)+P(B)

The probability that Zhi Qing chooses is either a three or a seven is 2/13.
