Answer:
Step-by-step explanation:
+(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5
−(−) 6−(−3) = 6 + 3 = 9
+(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5
−(+) 8−(+2) = 8 − 2 = 6
If you were to write it fully, as an equation, I believe it would look like this:
x²(4x-x) *4x
Therefore allowing you to simplify the area within the bracket into:
x²(3x)*4x
To expand, you simply start on the left and work your way across.
3x³*4x= 12x⁴
The price of third MP3 player is $58.40
Step-by-step explanation:
Given,
Cost of one MP3 palyer = $56
Cost of another MP3 player = $62
Average price of MP3 player = $58.80

Cost of third MP3 player = x
Average = 
Multiplying both sides by 3
The price of third MP3 player is $58.40

The circumference (perimeter) of the tire is 2 x π x r (radius= half of the diameter):
So one complete rotation is equivalent to the perimeter that is 2 x 13 x 3.1459
= 81.68 inches & if he competed 10 rotation that means he run for 10 x 81.68 ===> 816.8 In
