Answer:
468
Step-by-step explanation:
8/4*234=2*234=468
Answer:
168
Step-by-step explanation:
24 times 3 is 72 then also 24 times 4 is 96 add that and get 168
They are 20km apart. because in one hour one car would travel 60km and the other 40km and 60-40=20
The are 40320 ways in which the 5 indistinguishable rooks be can be placed on an 8-by-8 chess- board so that no rook can attack another and neither the first row nor the first column is empty
<h3 /><h3>What involves the
rook polynomial? </h3>
The rook polynomial as a generalization of the rooks problem
Indeed, its result is that 8 non-attacking rooks can be arranged on an 8 × 8 chessboard in r8.
Hence, 8! = 40320 ways.
Therefore, there are 40320 ways in which the 5 indistinguishable rooks be can be placed on an 8-by-8 chess- board so that no rook can attack another and neither the first row nor the first column is empty.

Answer:
-3
Step-by-step explanation:
The slope formula is y2-y1/x2-x1, so replace the variables with the given values.
-5-5/1-x= -5/2, now multiply both sides by "1-x"
-5-5= -5/2(1-x) or -10=-5/2+5/2x, now add 5/2 to both sides
-20/2+5/2=5/2x, now simplify the equation
-15/2=5/2x, multiply both sides by 2/5
-30/10=x or x is -3
