A rectangle’s length is 2 units more than twice its width. Its area is 40 square units. The equation w(2w + 2) = 40 can be used
to find w, the width of the rectangle.
2 answers:
Answer: Value of w is 4 units and the equation is correct.
Step-by-step explanation:
Let width of a rectangle be 'w'.
Let length of a rectangle be '2w+2'.
Since we have given that
Area of rectangle = 40 square units.
As we know the formula for "Area = Length × Breadth" :
So, it becomes,
But dimension can't be negative.
So, w must be 4 units.
Hence, Value of w is 4 units and the equation is correct.

Answer:
The probability that Alice wins the game=
Step-by-step explanation:
We are given that Alice and Bob are playing a game .
We have to find the probability that Alice wins the game .
If Alice win when she gets head and lose when she gets tail.Bob wins when she gets tail and she lose when she gets head.
Total results in a coin=Head, tail=2
Number of head in a coin=1
Number of tail in a coin= 1
Probability is defined as the possibility of an event that occurred
The probability that Alice wins the game=
The probability that Alice wins the game=
The probability that Alice wins the game=
