Determine the x-intercept points of the function h(x) = (x - 5)(x-6)(x + 4). A. (-4,0), (5,0) and (6,0)

B. (4,0), (5,0) and (6,0)

C. (-6,0), (-5,0) and (-4,0)

D. (4,0), (-5,0) and (-6,0)

A.

Step-by-step explanation:

The x-intercepts are the points where the x value is zero. In this case, to find the "zeros" of the function, set each factor to zero. x-5 -> x=5. x-6 -> x=6. x+4 -> x=-4.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
