Answer:
Step-by-step explanation:
The given expression is:
-3(6f - 12) = 36 - 18f
To prove that L.H.S=R.H.S:
Multiply -3 (6f-12)
-3(6f)-3(-12)
=-18f+36
=36-18f
Hence it is proved that L.H.S = R.H.S....
Answer: x^2 - 8x + 16
Let y = x-4
(x-4)^2 = (x-4)*(x-4)
(x-4)^2 = y*(x-4) ... replace one copy of (x-4) with y
(x-4)^2 = x*y - 4*y .... distribute
(x-4)^2 = x*( y ) - 4( y )
(x-4)^2 = x(x - 4) - 4(x - 4) ... replace y with x-4
(x-4)^2 = x^2-4x-4x+16 .... distribute
(x-4)^2 = x^2 - 8x + 16
There are 53 silverware
There are 11 forks in the silverware in the drawer
There are three more knives and forks
There are twice as many spoons and knives
The number of silverware can be calculated as follows
= 11 + (11 +3) + 2(11 +3)
= 11 + 14 + 2(14)
= 25 + 28
= 53
Hence the number of silverware pieces is 53
