Lu is making a quilt that is 20 squares wide and has 24 rows. the border of the quilt is made by using each toy design equally as often. each square can only hold one design. how many of each design does she use for the border

The border will have 20 squares two times, and 24 squares two times as well, that is the perimeter or the border, because a quilt has 4 sides:
20*2 + 24*2 = 40 + 48 = 88
So the border will have 88 squares total. So if the border can have only one design, Lu can use any toy design 88 times if she wants the border to have the same toy design in it.

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2

Ithink the answer is: it is likely.
