Answer:28
Step-by-step explanation: 6.4x6.4 = 40.96
3.6x3.6=12.96
To evaluate the expression (6.4)² - (3.6)², square each of the numbers and then subtract the square of 3.6 from the square of 6.4 to give a result of 28.
The question asked is mathematics related and it requires to evaluate an expression: (6.4)² - (3.6)². This is a simple arithmetic problem that involves squaring numbers and subtraction.
Firstly, squaring a number means multiplying the number by itself. Hence, (6.4)² equals to 6.4 * 6.4 which gives 40.96. Similarly, (3.6)² equals to 3.6 * 3.6 which gives 12.96.
Then, subtract the squared number of 3.6 from the squared number of 6.4. That is: 40.96 - 12.96, and you'll have your answer, which is 28.

Answer:
x = 1/2 = 0.5
Step-by-step explanation:
We must solve x in the following equation:
–3x + 1 + 10x = x + 4
We'll try to get the terms with x on the left and the independent terms on the right by performing the opposite operations on both sides of the equation:
–3x + 1 + 10x -x = x + 4 -x
–3x + 1 + 10x -x -1 = 4 -1
6x = 3
Now lets isolate x, again by performing the opposite operation, that is dividing by 6 on both sides:
6x /6 = 3/6
x = 1/2 = 0.5
Question is not clear enough
I'll assume the question is this:
A fair coin has 2 sides (heads and tails) that are equally likely to show when the coin is flipped. What is P(tails)?
Answer:
P(tails) = 0.5
Step-by-step explanation:
Given:
Number of sides = 2
Number of head = 1
Number of tails = 1
Let P(Tail) = Probability of obtaining a tail when the coin is flipped.
P(Tails) is calculated as follows;
P(Tails) = Number of Tails/Total Number of Sides
Substitute in the values of Number of Tails and Total Number of Sides
P(Tails) = 1/2
P(Tails) = ½
P(Tails) = 0.5
Hence, the probability of obtaining a tail provided that the two sides of the coin are equally likely to show when the coin is flipped is 0.5
