9 is your answer, hope this helps
Answer:
Step-by-step explanation:
I think you are to assume that this is a trapezoid and that the top right angle symbol is missing.
Area = (b1 + b2 ) * h /2
Givens
b1 = 2
b2 = 6.2
h = 3
Solution
Area = (2 + 6.2)* 3 / 2 Combine what is inside the brackets
Area = 8.2 * 3 / 2 Divide by 2
Area = 4.1 * 3 Combine
Answer: Area = 12.3
2.04 divided by 4 is £0.51 per roll
4.68 divided by 9 is £0.52 per roll
4 pack is better deal because the 9 pack is more per roll
The given quadratic equation will not have any real solution for c<-9/4.
The given quadratic equation is:

<h3>What is a quadratic equation?</h3>
Any equation of the form
is called a quadratic equation with a≠0.
In order to have no real solution, the discriminant of a quadratic equation will be less than zero.




For
the given quadratic equation will have no real solutions.
