Answer: 24
Step-by-step explanation: 4*12=48 and 8*3=24 then subtract 24 from 48 and you get 24
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
Answer: a = 64
Step-by-step explanation: the equation for area is a=lw. a = 16(4) which is equal to 64.
