2x8nd<span>4 theres your answer</span>
Answer:
Step-by-step explanation:
x(3x+2)=16
3x²+2x-16=0
3x²+8x-6x-16=0
x(3x+8)-2(3x+8)=0
(3x+8)(x-2)=0
either 3x+8=0
x=-8/3(rejected as width can't be negative)
x-2=0
x=2
so width=2
length=3×2+2=6+2=8
7*X(number of students)=y(total cost)
The independent variable is the number of students and the dependent variable is the cost in dollars. I hope I helped!
