Answer:
172 yd²
Step-by-step explanation:
To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20
It has to be equated to zero and the values of x are the x-intercepts. So,
4x2 – 24x + 20 = 0
The resulting equation is a quadratic equation which can be solved by different methods. The solution is
x = 5, 1
The average therefore is:
(1+5/)2 = 3
31.08...........................
70/100 in simplist form is 7/10 because you divide each side by 10 to get 7/10
