One number is 6 more than another. the difference between their squares is 192. what is the numbers?

Masteriza [31]

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!

BRAINLIST ANSWER- You and your friends want to rent a limo on prom night. The limo costs $75 per hour plus a $50 booking fee. Yo

Lelu [443]

First, you would want to subtract the booking fee from the total amount of money you have to spend. 350-50 = 300.
After paying the booking fee, you would have 300 dollars left to spend. Now, divide the amount of money you have left in all by the cost per hour. 300/75 = 4.
The answer is B, because you can have the limo for 4 hours.
Hope that helped you.
