Answer:
48x^2-10x-72
Step-by-step explanation:
What you do is the distributive property but at one time.
So you will multiply 6x to all the numbers. Then you will multiply -8 to all the numbers.
6x(3x+5x+9)=18x^2+30x^2+54x.
-8(3x+5x+9)=-24x-40x-72.
You will then add them together to get
48x^2-10x-72 as your answer.
Indicated here when h(t) = 0, we are to find for the time where the football has reached a certain height.
Then, the values of t would be -0.2 and 2.7.
Since we are to look for the time, it is impossible for us to have an answer that has a negative value. So based from our answer, the solution that we will eliminate is the -0.2 one. Since its value is negative.
So, the correct value would be the 2.7 sec. one.
The answer is 3 1/2 divided by 1 1/2 because those equal 7.
