The perimeter of the triangle is: 4x+9
Step-by-step explanation:
Perimeter is the measurement of boundary of any closed figure.
Given
s1 = x+4
s2 = x+8
s3 = 2x-3
So, the perimeter will be the sum of all three sides
![P = s_1+s_2+s_3\\= (x+4) + (x+8) + (2x-3)\\= x+4+x+8+2x-3\\= 4x+9](https://tex.z-dn.net/?f=P%20%3D%20s_1%2Bs_2%2Bs_3%5C%5C%3D%20%28x%2B4%29%20%2B%20%28x%2B8%29%20%2B%20%282x-3%29%5C%5C%3D%20x%2B4%2Bx%2B8%2B2x-3%5C%5C%3D%204x%2B9)
Hence,
The perimeter of the triangle is: 4x+9

We have that
<span>y = -x</span>²<span>+8x
we know that
when the ball hint the ground is the x-intercepts of the graph
the x-intercepts is for y=0
so
0=-x</span>²+8x--------> x²-8x=0----> x*(x-8)=0
the solution is
x=0
x=8
the x intercepts are the points (0,0) and (8,0)
the distance between the x intercepts points =[8-0]-----> 8 ft
the answer is
8 ft
see the attached figure
