Answer:
see in the picture, the perimeter of this rectangle is
2( x + 3x) = 8x but the perimeter is 65.6
=> 8x = 65.6
<=> x = 65.6/8
=> x = 8.2
By the Pythagorean theorem,
Absolute value is the magnitude of a number without regard to its sign. for example, the absolute value of 5 is 5, and the absolute value of -5 is also 5!
Multiplication would be the inverse operation of division. so it would be, 3 x 34 = 102
100%-20%=80%
discount:250*20%=50
price of soft drinks:250*80%=200
