If one ratio is equivalent to another, that means that you multiply the top and the bottom on one ratio by a constant to get the larger ratio. D does that here for us. We have to multiply 3 by 5 to get to 15, so 16 times 5 better be 80 and it is.
Width: x
Length: 1/6x-1
Perimeter
=x+x+1/6x+1/6x-1-1
=14/6x-2
=7/3x-2
Im going to say the answer is C
Answer:
something something
Step-by-step explanation:
Answer:The equations of the bisectors of the angles between 3x - 4y + 7 = 0 and 12x - 5y - 8 = 0 are

12x−5y−8
or 39x−52y+91= ± (60x−25y−40)
Taking the positive sign we get 21x+27y−131=0 as one bisector
Taking the negative sign we get 99x−77y+51=0 as the other bisector
