In the quadratic equation x2 - 8x + a = 0; what is the value, a, in order to form a perfect square?

16

Step-by-step explanation:

(x - y)² = x² - 2xy + y²

x = x and y = a

2xy = 8x

2*x*a = 8x

     a =

a = 4

a²  = 16

24: 56

step-by-step explanation:

24 can be divided into 3 and 56 can be divided into 7, where as all the other ratios can't.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
