Answer:
14 ft
Step-by-step explanation:
Given:
- Bedroom is 4 ft longer than it is wide.
- Area is 252 ft².
Let x = width of the bedroom:
- width = x ft
- length = (x + 4) ft
Therefore:

To find the value(s) of x, complete the square.
Add the square of half the coefficient of the term in x to both sides:


<u>Factor</u> the perfect trinomial on the left side:

<u>Square root</u> both sides:


Therefore:


As width cannot be negative, the width of the room is 14 ft.

Answer:
probability that Caroline buy both CD and fruit = 0.52
Step-by-step explanation:
We have given that the probability of Caroline buys a fruit P = 0.4
So probability of Caroline does not buy the fruit = 1 - 0.4 = 0.6
Probability Caroline buys a CD P = 0.2
So probability of Caroline does not buy the CD = 1 - 0.2 = 0.8
So probability that Caroline does not buy either buy CD or fruit = 0.8×0.6=0.48
So probability that Caroline buy both CD and fruit =1-0.48 = 0.52
It would be 8 to the 8th power
