Answer:
x² - 8x + 20
= x²- 2*4*x + 16 + 4
= x²- 2*4*x + 4² + 4
= (x - 4)² + 4
= (x - a)² + a, with a = 4
Hope this helps!
Model mural::
L*W = 0.3 sq. ft
--------------
Actual mural::
(5L)(5W) = 25*LW = 25*0.3 = 7.5 sq ft.
If you initially have 6 W, 4 R, and 8 B, and you take away two whites and a red, then you have 4W, 3 R and 8 B. There are 15 marbles total, and 8 black marbles, so you have an 8 in 15 or 53% chance of picking a black marble.
The answer would be : 0.
Hope this helps !
