X = 2
A square has 4 sides. To get the perimeter of a square, you could multiply the length of one side by 4.
One side of the larger triangle is x inches plus an additional 8 inches, which can be written as (x+8)
To get the perimeter of the larger square, multiply the expression (x+8) by 4. The question states the larger square’s perimeter is 40 inches.
You end up with this equation: 4(x + 8) = 40
To solve first distribution 4 into (x + 8).
4x + 32 = 40 | subtract 32 from both sides
4x = 8 | divide each side by 4
x = 2 inches
So the side length of the original square is 2 inches. To check your work, go back and plug x = 2 into the original equation. 8 in + 2 in = 10 inches, and 10 inches x 4 = 40 inches, so x = 2 is the solution
Answer: EX:There are 10 numbers from 1 - 10
first we get the numbers less than 2 are (1)
secondly get the numbers greater than 7 are (8,9,10)
total = 4 numbers
The favorable probability is 4 / 10=2 / 5
hope it helps

Answer:
Step-by-step explanation:
Total distance = 3 + 2.5 = 5.5mi/h
Total time = 0.75h + 2hr = 2. 75 hr
Average speed = 5.5 / 2.75 = 2
