Is it possible for a knight to move around an 8 × 8 chessboard so that it makes every possible move exactly once (consider a move between two squares con- nected by a knight to be completed when the move is made in either direction)?

im pretty sure its

(8,15)

step-by-step explanation:

if the probability is 1/12, 75 people will receive a $25 gift card

step-by-step explanation:

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
