Answer:
Hi how are you doing today Jasmine
12/2 = 6, so;
7x-1 = 6
7x = 7
x = 1
Because both sides are equal, you do the same for 2x+4
2x+4 = 6
2x = 2
x = 1
Display board measurements = 10ft by 6ft
So all the sides would be 10ft, 10ft, 6ft, 6ft
Add them all together= 32ft
Ribbon length would need to be 32ft long
