Answer:
x³-9x²+27x-27
Step-by-step explanation:
(x-3)³
EXPAND
x³-3x²×3+3x×3² -3³
COMBINE
x³-9x²+3x×9-27
multiply 3x ×9
x³-9x²+27x-27
269, it would be like dividing 4 to the 8th power by 2
Answer:
Given:
To calculate how many electrons have the same mass as one dust particle, divide the mass of a dust particle by the mass of an electron:
Therefore, approximately 
electrons have the same mass as one dust particle.
1 pound = 16 ounces.
there are 3 ponds and 6 ounces
3 * 16 = 48
48 + 6 = 54
Nancy bought 54 ounces of ground chunk beef
s=1/23
given equation in term of s is 12+3/2s-1/2-3/4s=5/4s
to solve this first we need to take LCM on left hand side and right hand side we can rewrite given equation as 12/1+3/2s-1/2-3/4s=5/4s now taking LCM of {1,2s,2,4s,4s} is 4s then the equation becomes 48s/4s+6/4s-2s/4s-3/4s=5/4s
(48s+6-2s-3) /4s=5/4s now cancel out denominator of both side we get 48s+6-2s-3=5 this implies 46s+3=5
46s=2
s=1/23
Hence the value of s is 1/23
