I think it is 49123.52
Step-by-step explanation:
Number 1:
9x^2 + 12x + 4 -> (3x + 2)^2
16x^2 + 24x + 9 -> (4x + 3)^2
2. x^2 + Bx + 64
B = (sqrt64) *2 = 16
3.
Solving equations like this requires completing the square, which has the first step of choice 4.
Answer:
The price of the drink is: $4
and the bag of popcorn costed $5.5
Step-by-step explanation:
Let b=the price of each bag of popcorn
Let d=the price of each drink
One bag of popcorn costs $b, so 10 bags of popcorn cost 10b. One drink costs $d, so 6 drinks cost 6d. The total cost 10b+6d equals \$79:
10b+6d=79
Likewise, if 3 bags of popcorn and 5 drinks cost $36.50, then:
3b+5d=36.50
Write System of Equations:
10b+6d=79
3b+5d=36.50
Here’s the answer, hope you understand
