Answer:
8 pounds(lbs)
Step-by-step explanation:
If a candy costs $7 per pound, $56 divided by $7 will equal 8 pounds.
Let the number be x.
then the number is (x + 6)
the difference between their squares is 192
(x + 6)² - x² = 192
expanding we get;
x² + 12x + 36 - x² = 192
12x + 36 = 192
12x = 192 - 36
12x = 156
x = 13
the numbers are 13 and 19.
hope this helps, God bless!
8 is to 64 as 2 is to 16
x=16
