Y^4-4y^3+7y^2-6y-2y^3+8y^2-14y+12=
y^4-6y^3+15y^2-20y+12
or
y^3-4y^2+7y-6=y^3-4y^2+4y+3y-6=
y(y^2-4y+4)+3(y-2)=
y(y-2)^2+3(y-2)=(y-2)[y(y-2)+3]=(y-2)(y^2-2y+3)
(y^3-4y^2+7y-6)(y-2)=(y-2)^2(y^2-2y+3)
Y=10
Y=7x
10=7x
7/10= 1.43
A.$1.43
1.43•5=$7.15
B.$7.15
I think this is the answer hope it helps
Answer:
No real solutions.
Step.-by-step explanation:
Step 1: Subtract 2x from both sides.
For this equation: a=1, b=-2, c=20
Step 2: Use quadratic formula with a=1, b=-2, c=20.
She'll pay 90% of the original price ($6), so that'll be $5.40.
She'll pay $5.40 for the beads.
The answer is 22,440......4 miles is 21,120 feet....1/4 of a mile is 1,320 feet.... so when you add em up you get 22,440 feet
