Answer:
hcf:3x^3-6x^2+y^2-3x+54
lcm:2(x+3)(x^2-3x+9)(x^3-3x^2+9)(y^2-3x+9)
Answer:
expected profit is - $0.50
Step-by-step explanation:
1 $(7.00) 0.166666667 $(1.17)
2 $(7.00) 0.166666667 $(1.17)
3 $1.00 0.166666667 $0.17
4 $1.00 0.166666667 $0.17
5 $1.00 0.166666667 $0.17
6 $8.00 0.166666667 $1.33
$(0.50)
P-4(p-2(3-p))=12 remove the parentheses
P-4(p-6+2p)=12 collect like terms
P-4(3p-6)=12 remove the parentheses
P-12p+24=12 collect like terms
-11p+24=12 move the constant to the right
-11p=12-24 calculate
-11p=-12 divide both sides
P=12/11
Alternative form
P=1 1/11
