Multiplicative Identity Property
Step-by-step explanation: The Product of what number times one will equal the same number.
------------------------------------
Define x :
------------------------------------
Let the width be x.
Width = x
Length = 4x
------------------------------------
Find x :
------------------------------------
Perimeter = 30 ft
2 (x + 4x) = 30
2(5x) = 30
10x = 30
x = 30 ÷ 10
x = 3
------------------------------------
Find Length and Width :
------------------------------------
Width = x = 3
Length = 4x = 4(3) = 12
------------------------------------
Find Area :
------------------------------------
Area = 3 x 12 = 36 ft²
------------------------------------
Answer : Area = 36 ft²

Answer:
Step-by-step explanation:
Given: Three yarn colors are red, black, and blue
To find: probability that the first color is blue and the second color is red
Solution:
Probability is the chance of occurrence of some event.
Probability = number of favourable outcomes/Total number of outcomes
Probability that the first color is blue = 
probability that the second color is red if the first color is blue = 
So,
probability that the first color is blue and the second color is red =
