Answer:
a. The variable X represents the amount of hot dogs
b. the variable Y represents the amount of sodas
c. Their total expense would be $13.50
If you multiply $1.50 by 7 you would get $10.50, then you would multiply $0.75 by 4 and get $3.00.
then you would add 10.50 and 3.00 to get $13.50
1963,50/8,50= 231
they need to sell 231 tickets
Answer:
i dont know how to help
Step-by-step explanation:
F ( x ) = ( x + 7 ) ( x + 4 ) - ( x + 5 ) ( x + 2 ) =
= ( x² + 4 x + 7 x + 28 ) - ( x² + 2 x + 5 x + 10 ) =
= ( x² + 11 x + 28 ) - ( x² + 7 x + 10 ) =
= x² + 11 x + 28 - x² - 7 x - 10 = 4 x + 18
Answer:
The area of the shaded region is 4 x + 18.
