Answer:
3x^2-6x+3=0
x^2-2x+1=0
x^2-x-x+1=0
x(x-1)-(x-1)=0
(x-1)(x-1)=0
x=1,1
so x has only one answer
so it intersects only one time
Answer:
choice B.
you pay .10 for each ounce
but in choice A you pay. 13 per ounce
Formula for Perimeter of Rectangle:
P = 2(L + W)
Plug in 160:
160 = 2(L + W)
L = 4W
So we can plug in '4W' for 'L' in the first equation.
<span>160 = 2(L + W)
160 = 2(4W + W)
Combine like terms:
160 = 2(5W)
160 = 10W
Divide 10 to both sides:
W = 16
Now we can plug this back into any of the two equations to find the length.
L = 4W
L = 4(16)
L = 64
So the width is 16, and the length is 64.</span>
