Answer:
The cost is the same after 15 video rentals
Step-by-step explanation:
Let the total cost be y
Let the number of video rentals made be x
Discount card for Big video = $9.99
Discount card for Main Street video = $20.49
Cost of 1 big video rental = $2.49
Cost of 1 Main Street video rental = $1.79
Cost of video rentals with big video:
Y = 9.99 + 2.49x………….(1)
Cost of video rentals with main street video
:
Y = 20.49 +1.79x…………(2)
For the two costs to be equal, the two equations have to be equal to each other
Equating equations (1) and (2)
9.99 + 2.49x = 20.49 +1.79x
0.7x = 10.5
X = 10.5/0.7
X = 15 video rentals
you have negative -12
turn this into a positive (12)
12 plus 18
= 30

3 (x2 + 10x + 25)
Factor using the perfect square rule.
And then your answer should be 3 ( x + 5) ^2
