You divide 12 by 1.56 because a dozen is 12 of something. This gives you about 8 cents per
X^2-6x+9=0 has only one solution
Hope this helps
9x²-0x-4
=9x²-4
=(3x-2)(3x+2) is the factor form of 9x²-0x-4
Solve for x:
3x-2=0
Add 2 to each side
3x-2+2=0+2
3x=2
Divided 3 to each side
3x/3=2/3
x=2/3
Or
3x+2=0
Subtract 2 to each side
3x+2-2=0-2
3x=-2
Divided 3 to each side
3x/3=-2/3
x=-2/3. Hope it help!
A. Both triangles equal 50 and 10x5 is 50. Therefore, y=5.
