Which Expressions?
Step-by-step explanation:
Answer:
if the order of the digit matters, we have:
options: 1, 2, 3, 4.
We want to select two digits.
First selection: we have 4 options
Second selection: we have 3 options (because we already selected one in the first selection)
The total number of elements in the sample space, or the total number of combinations, is equal to the product of the number of options in each selection, this is:
P = 4*3 = 12
Answer:
6 ft
Step-by-step explanation:
Let the width = w
Then the length = 4w - 3
perimeter = 2(length + width)
perimeter = 2(4w - 3 + w)
perimeter = 2(5w - 3)
perimeter = 10w - 6 = 54
10w - 6 = 54
10w = 60
w = 6
Answer: The width is 6 ft
