B should be the answer but I’m not that sure
ANSWER : (9u - 8)2
STEPS:
Step-1 : Multiply the coefficient of the first term by the constant 81 • 64 = 5184
Step-2 : Find two factors of 5184 whose sum equals the coefficient of the middle term, which is -144 .
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and -72
81u2 - 72u - 72u - 64
Step-4 : Add up the first 2 terms, pulling out like factors :
9u • (9u-8)
Step-5 : Add up the four terms of step 4 :
(9u-8) • (9u-8)
Which is the desired factorization
Volume of one cubic block = (1/6)^3 = 1/216 cu ins
Volume of the prism = 1/3 * 2/3 * 2/3 = 4/27 cu ins
Number of blocks to fill prism = 4/27 / 1/216 = (216*4) / 27 = 32
Answer:
Step-by-step explanation:
The equation of a line:
We have
substitute:
The formula of a distance between a point and a line:
General form of a line:
Point:
Distance:
Convert the equation:
|<em>subtract 
from both sides</em>
|<em>multiply both sides by 3</em>
Coordinates of the point:
substitute:
|<em>multiply both sides by 
</em>
|<em>divide both sides by 3</em>
Finally:
